Análise bibliométrica da produção científica sobre patologias observadas em estações de tratamento de água
(2021-07-16) Silva, Juliana Sandrely da; Galvão, Simone Perruci; Cavalcanti, Maurício Pimenta; http://lattes.cnpq.br/9151405767773864; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/0232118019455098
This work is a narrative bibliographic review on the survey of the main pathological manifestations found in Water Treatment Plants (WTP) and their origins, causes and mechanisms. The aqueous environment in which the reinforced concrete structures are inserted in the treatment units is a facilitator for the action of aggressive agents, intensifying their action mechanisms and their deleterious effects, providing the appearance of pathological manifestations. After analysis, discussion and theoretical basis provided by scientific research on the subject, the visualization of the degree of criticality of the manifestations discussed was performed, through the use of the GUT prioritization matrix, in order to relate the anomalies with their priority for resolution. Thus, it was observed that the structural elements that are affected by corrosion of the reinforcement should be prioritized as to the degree of risk and intervention. It was also possible to see the relevance of treating pathological manifestations such as surface wear by erosion, leaching, cracking and carbonation. The extreme importance of corrective maintenance is evident, while the need for effective compliance with preventive maintenance is even more highlighted.
Análise comparativa de preços e índices entre o SINAPI e apropriação em obra de edificação na cidade de Recife-PE
(2024-08-15) Silva Júnior, José Carlos da; Verás, Juliana Claudino; http://lattes.cnpq.br/8199104094050794; http://lattes.cnpq.br/3351881847848169
The budget of a construction project is essential in the civil construction industry, influencing business relationships and the feasibility of projects. Cost engineering professionals and construction companies use cost reference systems, such as the National System of Research on Costs and Indices of Civil Construction (SINAPI), created in 1986 by the Caixa Econômica Federal. SINAPI standardizes public work budgets by collecting data on consumption, productivity, and prices, especially in the residential sector. This work aims to conduct a comparative analysis between the cost compositions of SINAPI and those assessed in the field by the author, highlighting the practical relevance for budgeting professionals. Understanding the differences between SINAPI references and actual values is crucial for more accurate estimates. The methodology combines qualitative and quantitative approaches to identify the most relevant services in the project budget. The ABC curve analysis was used to classify services based on their financial importance. Unit cost compositions were developed using SINAPI data from August 2023, extracting consumption indices for materials, labor, and the unit cost of inputs. A critical analysis was also conducted on the variations between SINAPI prices and those practiced in the market. During the analysis, it was noted that SINAPI prices do not always reflect the negotiating power of construction companies, which often negotiate bulk purchases, resulting in the underestimation of compositions for larger projects. Items not included in SINAPI's compositions were frequently identified, impacting the final budget. However, consistency in productivity indices was observed in most compositions. The analyzed services showed a negative deviation of 2.66% in total cost compared to SINAPI's compositions, but individual deviations varied significantly, with differences reaching 60.94% negative and up to 28.26% positive. The analysis highlights the importance of a critical approach in budget preparation. Although SINAPI is a valuable reference, it is essential for professionals to consider the specificities of each project and adjust the compositions as necessary. The balance between standardization and flexibility is crucial for more accurate and well-founded estimates.
Análise de mapa de danos das fachadas de igrejas históricas tombadas localizadas no município de Jaboatão dos Guararapes
(2017-08-29) Silva, Anderson José da; Araujo, Fernanda Wanderley Correa de; http://lattes.cnpq.br/7616387320307731; http://lattes.cnpq.br/0895425089026343
The facade of a building is the system that first impresses people. In this sense, they can cause the appreciation or the devaluation of the property, depending on parameters such as the presence of pathologies and the architecture employed. The historic building will always present a greater difficulty to appreciate its facade, since the external agents have caused a constant decrease of its useful life over the years. The present study intends to analyze how the current state of conservation of the main facades of the historical churches is located in the municipality of Jaboatão dos Guararapes through the construction of damage maps. In this context the buildings treated were: the Church of Our Lady of Piedade, the Church of Our Lady of Prazeres and the Church of Our Lady of Loreto. It was necessary to make a bibliographical survey about the most recurrent pathologies to these systems and obtained the following parameters: mold / mildew, paint stripping, vegetation, detachment and cracks. For the recognition of these pathological manifestations, techniques were used for preliminary inspections, with on-site visits, visual inspections and photographic records. After due treatment of the data, it was observed that the humidity and the precipitation incidence were the factors that contributed the most to the pathologies in these frontispieces, because both contributed to the proliferation of fungi and vegetation and to the superficial erosion of the rocks.
Análise de viabilidade entre concretos dosados pelos métodos da ACCP/ACI e IPT/USP
(2019-07-08) Nascimento, Lucas Costa do; Araújo, Fernanda Wanderley Correa; http://lattes.cnpq.br/7616387320307731; http://lattes.cnpq.br/7949189322240161
The proper determination of the proportion of materials in the production of a concrete can imply a significant reduction of the final cost of work, since it is one of the materials most used in construction. The wide use in civil works indicates the need to rationalize the quantity of materials composing the mixture by determining an efficient feature that allows an adequate interconnection between the different physical properties required of a concrete with the lowest possible cost. This study presents a comparative analysis of physical and mechanical properties, material consumption and cost between two dosing methods: the one proposed by the Brazilian Portland Cement Association (ABCP), which is an adaptation of the ICA method, and the experimental method IPT / EPUSP. From initial parameters (concrete volume, compressive strength, cone trunk abatement and physical properties of cement and aggregates) and following the prescriptions and steps described by the methods, the respective traces were determined for the molding of a certain amount of ruptured specimens aged 14 and 28 days. With the obtained data, it was verified that both methods are able to provide concretes with the predefined physical properties. In terms of cost, the financial analysis of material consumption, based on the reference prices of the National System of Costs Survey and Civil Construction Indices (SINAPI / PE April-2019), verified a greater material saving by the IPT / EPUSP.
Análise dinâmica de estruturas treliçadas utilizando o método dos elementos finitos
(2021-03-05) Ferreira, Lenilson Régio; Ribeiro, Paulo Marcelo Vieira; http://lattes.cnpq.br/0171120821110850; http://lattes.cnpq.br/2234155499243922
It is noticed that currently there has been a significant increase in relation to the creation of source codes and/or computer programs for structural design purposes, and several are the languages that are used for such creations, in this work a source code was developed in the Matlab language, where the main objective of it aimed to build a code based on the Finite Element Methods - FEM, where we can solve dynamic problems of truss structures with point efforts applied to nodes, so that static (displacement) and dynamic (natural frequencies and vibration modes) information of the structure was obtained, and in parallel a comparison of these results was performed with a program already renowned in the market, which in this case was SAP2000, where it aims to facilitate the understanding of the application of this method to students and newly graduated engineers, in order to reduce errors in calculations related to structural analysis. The results obtained from the comparison were very close, with very little difference between the values. In the case of static analysis nodal displacements, the results were exactly the same. The natural frequencies and vibration modes, on the other hand, gave a difference that is practically negligible. In general, it was possible to validate the formulation developed in this work, since both paths gave results converging to the same point.
Análise dos recalques diferenciais em um reservatório de água elevado localizado no CEASA-PE
(2022-10-10) Augusto Filho, Ricardo; Borgatto, André Vinicius Azevedo; Silva, Jordlly Reydson de Barros; http://lattes.cnpq.br/4382584044561547; http://lattes.cnpq.br/4203791139862449; https://lattes.cnpq.br/2300010878356438
After inspections on a raised reservoir located in the Central Supply and Logistics of Pernambuco (CEASA-PE), structural pathologies were detected due to differential settlements, verified by topographic methods. The steps for the structural recovery of the superstructure were already in progress, requiring a solution for the stabilization of the settlements in order to prevent new pathologies or the collapse of the construction. This paper presents a case study of the problem cited, discussing the causes, effects and possible solutions, with the main focus on the analysis of settlement predictions and actual settlements, taking into account factors, economic, structural and usability. First a structural analysis of the first order was performed in order to estimate the load that each column is transmitting to the foundation, being separated between preliminary and through structural software. Knowing the acting loads, along with geological data from the terrain, calculations were made to determine the geotechnical load capacity in the foundation region using semi-empirical methods, and after that, analysis of settlement predictions using parameters obtained through back analysis, in order to compare the results to real settlement magnitudes measured by topographical methods. The present work has as its objective, the understanding about the methodology used at the analysis of settlements in elevated reservoirs, serving as study material to help the resolution of similar problems.
Análise dos tipos de cura e sua influência no ganho de resistência à compressão em um concreto convencional
(2019-07-08) Silva, Jéssica Ferreira da; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605
The curing procedure consists of protecting the surface of the concrete from the environment to which it is exposed, avoiding the excessive loss of water from kneading and early formation of cracks. Is essential for the development of concrete strength and for its integrity in the first moments of the hydration. The order to analyze the different curing methods and their influence on the property of characteristic resistance to the compression of a conventional concrete for 30MPa, it work examined three types of cure, among them: thermal cure at 70ºC, wet cure by immersion in water and wet cure by immersion in calcium hydroxide solution. For the thermal curing a device was developed using the Arduino so that the expected conditions were reached. From the analysis obtained in this work it was observed that the thermal and wet curing by immersion in water were more effective at the age of 7 days, compared to the wet curing in saturated lime solution. At 28 days, the cure by immersion in calcium hydroxide solution showed the highest strength gain compared to other types of cure, showing an increase of 1.42 MPa compared to the cure made by immersion in water for 3 days, and 1.97 MPa in relation to thermal cure.
Análise estrutural de placas retangulares submetidas a carregamentos estáticos trapezoidais
(2019-07-12) Santana, Vitor Carneiro de; Melo, Weslley Imperiano Gomes de; http://lattes.cnpq.br/4789771132461158; http://lattes.cnpq.br/6721685438361084
One of the fundamental steps in structural design is the internal force analysis and initial displacements of a given element when it is subject to an external loading. In the case of surface structural elements, this analysis becomes more complex due to the two-dimensional effect on bending forces, requiring the use of methods that describe the structure behavior in a simplified manner. One of the methods commonly used in plates is the static plate analysis according to Kirchoff's theory for thin plates, where, by solving the differential plate equation (also called the Sophie-Germain-Lagrange equation), tables are generated for the calculations of internal forces and deflections. One of the crucial parameters of differential stress and transverse displacement equations is the Poisson's ratio, which is commonly set at a value of 0.20 for concrete slabs. This study presents an analysis of the influence of Poisson’s ratio variation on internal forces and deflection of simply supported plates, subjected to linearly distributed loads (trapezoidal shape). For this, from the resolution of the Sophie-Germain-Lagrange differential equation by the Navier method, calculation tables were generated for constant and triangular loads, with the Poisson’s ratio ranging from 0.00 to 0.40. These tables were validated by comparative analysis of the results with established bibliographies and the ANSYS Student 2019 R1 software, obtaining percentage differences of up to 3.19% and 7.12% for constant and triangular loading, respectively. From the results, it was verified that the increase in Poisson’s ratio values resulted in larger bending moments and in the reduction of torsional moments and shear forces.
Análise estrutural e econômica de pavimentos flexíveis com adição de RAP na camada de revestimento, dimensionados pelo método do DNER e MeDiNa
(2024-03-07) Silva, Carlos Henrique Cordeiro da; Costa, Laiana Ferreira da; http://lattes.cnpq.br/4147758573818185; http://lattes.cnpq.br/8220012340940005
The Brazilian construction industry has been encouraged to invest in materials technology, mainly those that meet the precepts of sustainability, and updates on methods for sizing flexible pavements, considering that a large portion of Brazil's road network consists largely of this type of pavement and has suffered from premature wear, leading to constant maintenance. The reuse of milled material, also called Reclaimed Asphalt Pavement (RAP), has emerged as an alternative for reducing paving costs and the environmental impact caused by this service. This research sought to make a structural and cost comparison of implementing pavements with the addition of RAP at rates of 0%, 10%, 30%, and 50% in the surface layer, sized by the method of the National Highway Department - DNER (1981) and by the National Sizing Method (MeDiNa). Initially, data collection was conducted from literature sources on the materials that would be used in the layers of the pavements studied. After sizing, a structural and implementation cost comparison was made for one kilometer of road for all the structures proposed in the research. Structure 01, with 0% RAP and sized by DNER (1981), had the lowest cost, however, upon analyzed by the MeDiNa, permanent deformation failure was observed in the first month of the project and fatigue at the 25th month of use. Structure 02, with 0% RAP, was the costliest among all, however, like the other structures sized by MeDiNa, it will withstand traffic demands over the project’s duration (10 years). The number of equivalent fatigue failure requests (Neq) between the structures showed that structure 02 is 67% more economical. For the other structures, as the RAP content increases, the implementation cost decreases, reaching a reduction of 79% for the structure with 50% RAP in its surface layer. Therefore, through the results obtained in the research, it was observed that MeDiNa proved to be more suitable for meeting the estimated project time, besides allowing the use of different types of materials available for pavement execution without compromising its efficiency, as is the case with recycled asphalt mixtures containing RAP. It was also observed that increasing the RAP content in the asphalt mixture reduces the cost of the structure, saving cost in pavement implementation.
Análise funcional e econômica da obra de requalificação da rua Iati – Jaboatão Guararapes com o uso dos parâmetros topográficos e do índice de suporte Califórnia
(2019-12-05) Brito, André William Barbosa; Francelino, Martônio José Marques; http://lattes.cnpq.br/5457079260891955; http://lattes.cnpq.br/1589879584642925
Brazil is a country in the world where its road network predominates over other modes. However, the low quality of existing infrastructures in the country is clear. One example is the large urban centers where they are increasingly suffering from flooding, poor street and avenue conditions and scarcity of resources to implement new infrastructure. In addition, in several works the use of practical knowledge not linked to the existing technicians is observed, which leads to reduce the durability of new constructions. In this context, this research aims to compare the functional and economic performance in the requalification of Rua Iati, located in Cajueiro Seco in Jaboatão dos Guararapes, carried out by the municipal administration of the city, with some project scenarios of that same street with various solutions that adopt topographic parameters and routine soil tests in road works. To develop this study, Iati Street georeferencing, soil testing based on the main ABNT and DNIT standards, plani-altimetric topographic survey, street design in software Autodesk Civil 3D, project budgets and street measurements performed were performed. based on the actual unit costs of the companies responsible for performing these urban infrastructure services in the city of Jaboatão. It is demonstrated that there is a high use of financial resources, lack of technical parameters used and a lack of visibility in the quality of services performed, which leads to a reflection on how to use economic resources and ensure durability in newly refurbished streets of the Brazilian cities.

Aplicação da tecnologia de medição individualizada de água com telemetria em clube visando a redução das tarifas atribuídas à geração de esgoto
(2022-10-11) Lemos, Ana Letícia Barbosa Ferreira; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/3834066130381907
With population growth, utilities have less and less control over the use of water and the production and direction of sanitary sewage in the network. Thus, it is very common to observe in the invoices issued by the concessionaires, the application of tariffs considering the calculation of the volume of sewage assigned as 100% of the supply value, that is, indicating that all water consumed is directed to the sewage system. In practice, this does not occur, as there are consumption points asinfiltration into the soil, evaporation or rainwater sewer system, demonstrating the need for quantification and monitoring so that the tariffs applied based on the precision of the volume spent. In this sense, the individualized measurement system (SMI) of water combined with telemetry is a current technique that presents efficiency in the calculation of the volume of water. Therefore, the objective of the work was to apply the SMI together with telemetry in the club Associação Atlética do Banco do Brasil of Recife (AABB). The study was carried out over a period of 4 months, where the survey of supply points that do not generate sewage was carried out, the installation of the SMI, the installation of telemetry, the monitoring and calculation of the discount to be considered in the invoice. After 3 months of evaluating the results, a total volume of 17,85% was found, demonstrating the importance of reducing the rate and controlling consumption.
Avaliação da viabilidade técnica de uma cinza do bagaço da cana-de-açúcar, beneficiada por moagem, para produção de concretos
(2023-04-17) Silva, Gabriel Moreira Santos; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/1025369292967009
Brazil, the largest sugar and ethanol producer in the world, has a large supply of sugarcane bagasse ash (SCBA) as waste from the agro-industry. Intending to reduce the environmental impact caused by this industry and contribute to the valorization of SCBA, this study investigated the technical feasibility of using SCBA in addition to Portland cement for the production of precast concrete elements. The ash collected from the industry was processed by dry grinding in a ball mill, optimizing the processing time for a fineness range of 1600 m²/kg. The processing time was improved for the first seven hours, reaching a Blaine fineness of 1400 m²/kg, renaming the sample to CB-1400, and proceeding with further characterization tests of the material regarding the pozzolanic properties of the ashes and the properties of concrete, such as slump, compressive strength, and water absorption. For comparison, concrete without ash (REF), with ash “in natura” without grinding (CB-SM) and with favored ash (CB-1400) were produced and two types of curing (wet curing and air curing) were performed. The results indicated that only the CB-1400 has possible pozzolanic potential and filler effect. In the evaluation of the concrete, in the fresh state, only the mixture with CB-1400 maintained the slump of reference. As for the properties of concrete in the hardened state, it was observed that the air curing process, practiced in the industry, did not significantly influence the strengths at 7 days and 28 days; as for the wet curing condition, the concrete CB-1400 showed higher compressive strength than the reference mix. As for water absorption capacity, all concretes were within the tolerance designated by NBR 8451-1 (2020). The SCBA benefited from the grinding followed by monitoring the fineness of the particles proved to be a viable alternative for concrete production and can contribute to reducing the environmental impacts of this agro-industry while generating economic value for the material.

Dams are engineering works whose function is to dam up a region to contain or accumulate liquid substances or a mixture of solid and liquid loads. In the mining area, these structures receive tailings and/or sediments from mining activities. The collapse of a dam results in social, environmental, and economic impacts, in most cases irreversible, as occurred in the Fundão and Córrego do Feijão Dams, in Minas Gerais. For this reason, the evaluation of dam safety is indispensable, as it will enable timely preventive and corrective interventions, for the safety of the structure, the environment, and third parties in its area of influence. This work presents a case study of a mining dam, whose purpose is the evaluation of geotechnical safety and classification of the structure according to current legislation, based on the current conditions of the dam. To reach these objectives, information about the dam was acquired and the instrumentation, internal drainage system and downstream slope stability were analyzed. Finally, it was concluded that, during the period analyzed, the structure presented acceptable geotechnical conditions, in addition to satisfactory safety factors according to NBR 13.028/2017. Regarding classification, according to ANM Resolution nº 95/2022, the containment dike is classified in relation to the Risk Category (CRI) is Low and in relation to the Associated Potential Damage (PDA) is Medium.
Avaliação do custo de produção, produtividade e qualidade dos sistemas de alvenaria estrutural com blocos de concreto e de paredes de concreto, na construção de salões de festas de condomínio residencial na Região Metropolitana do Recife

Building systems for residential condominiums are increasingly associated with characteristics such as short schedules, good quality and low cost. Therefore, a designer can opt for the structural masonry system, using reinforced concrete walls or structural concrete blocks, for example, depending on the purpose of the construction process and aspects such as cost or productivity. The construction of cast-in-place concrete walls, to the detriment of structural concrete blocks, has become an excellent alternative for construction companies, due to the speed of production. On the other hand, masonry with structural blocks, despite dispensing with the use of forms, which have high costs, require longer execution time. This article presents a case study, based on an analysis of two types of masonry systems, the result of monitoring the construction processes and comparisons between them, using non-conformities, control of the executive process, productivity and costs as general parameters. direct. The analyzes were carried out following the construction of ballrooms, in two condominiums, of two works located in the Metropolitan Region of Recife. Through simple methodologies and tools available at the construction site, it was possible to obtain information to generate comparative indices between the respective construction methods, in order to analyze costs, productivity and quality. The study concluded that for each type there are advantages and limitations, therefore, the most relevant parameters should be analyzed in the design decision, generally considering factors such as costs and productivity. In this study, the system adopted with structural blocks provided the greatest advantage, due to the cost parameter, which is a determining factor for the company to choose projects with this constructive system for the annexes, such as the ballroom.
Caracterização físico-química e avaliação da qualidade das águas subterrâneas em poços da comunidade de Itapuama, Cabo de Santo Agostinho/PE

The use of wells to obtain underground water resources has become a complementary alternative for human supply. However, over the years, high consumption and anthropic action have contributed to the scarcity of groundwater and its contamination, have contributed to the contamination of groundwater, making it an agent that transmits diseases caused by pathogenic microorganisms from percolation of domestic sewage and/or chemical matter in concentrations that exceed the standards authorized by the Ministry of Health and CONAMA 357/2005, of the Ministry of the Environment. The aim of this study was to analyze the physical-chemical parameters: pH, dissolved oxygen, electrical conductivity, total dissolved solids, salinity, color and turbidity and to evaluate water quality by the Most Likely Number (NMP.100 mL-1) of total coliforms and thermotolerant, based on current legislations. In −1 total, 120 samples were analyzed for physical-chemical characterization and 6 for microbiological, from three wells in the community of Itapuama, located in the city of Cabo de Santo Agostinho - PE. Of the evaluated wells, two did not comply with the quality standard established by Brazilian legislation. The results showed a high concentration of electrical conductivity, low dissolved oxygen and high levels of microbial contamination. These non-conformities can originate from the inefficiency of the neighborhood's sewage system. The third well, since it is a phreatic tubular well, presented good quality water in the studied parameters, being above the limit only in the electrical conductivity parameter.
Classificação dos resíduos de construção e demolição (RCD) e potencialidades de reciclagem ou reutilização em obras de edificação na região de Ipojuca: Muro Alto
(2017-09-01) Nascimento, Lucas Costa do; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/7949189322240161
The environmental concern is recurrent in today's world, and the practices developed by both society and government aim to reduce the number of waste disposed indiscriminately in the environment are inevitable. Construction and demolition waste (RCD) discarded and exposed irregularly in the urban environment, generates the proliferation of vectors, among other negative aspects, being this over the years studied, assuming a possible material potential for reuse. With the objective of quantifying and characterizing the types of construction and demolition residues from buildings (vertical constructions) in the city of Ipojuca: Muro Alto, and later establishing a specific use for the reuse of these wastes, a field research was carried out , from questionnaires and the consultation of PGRCCs of medium and large companies, in the indicated districts. It was concluded that large construction companies that have certifications such as ISO 9001 and 14001, follow, in great part, waste management policies. Meanwhile, the medium-sized construction company analyzed, without strict control and planning, the RCD generated on site. Much of the waste generated by the companies is rubble or debris: remnants of mortars, concrete - demolition, remains of tiles, class A waste, which can be reused and recyclable.
Classificação e quantificação dos resíduos de construção e demolição (RCD) e suas pontencialidades de reciclagem ou reutilização em cinco obras de edificação na cidade do Recife
(2017-08-30) Amorim Júnior, Laelson de Andrade; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/7943300714310248
The city of Recife, region with several natural landscapes and attractive for tourism, business and leisure, has been developing annually. In most of the neighborhoods, there are large buildings being erected, leading the academic community and the state to worry about the type of policy adopted for the disposal, reuse and recycling of solid waste generated in construction, in order to avoid the environmental impact. In the Northeast Region of Brazil alone, 24,310 t / day of construction and demolition waste (CDW) were collected. Good results have already been visualized by Brazilian researchers regarding the reuse of residues, especially those of class A, generated on site. This work has proposed to classify the different types of construction and demolition waste and to indicate different forms of reuse in construction works in the city of Recife. Five (5) works were evaluated, from four (4) companies, located in different districts of Recife. To obtain the desired data, an electronic questionnaire, google forms platform, was developed by the research group. The construction traditional system of reinforced concrete was the main visualized in the works analyzed, generating as main types of residues: ceramic bricks, mortars, plaster, concrete and wood. In this work, recycling practices were verified in one of the analyzed companies, where brick and tile residues were reprocessed and used as a small aggregate for making mortars and lean concrete. However, the vast
