Item Estudo do comportamento mecânico de estruturas submetidas a corregamento estático(2019-01-31) Araujo, Joice Ferreira Nunes de; Silva, Jordlly Reydson de Barros; http://lattes.cnpq.br/4382584044561547; http://lattes.cnpq.br/6554335127800409During the structural design, it is essential to know the mechanical behavior of structural elements once it enables to understand the deformation and the internal forces acting in the system. However, until the mid-twentieth century, for certain types of structures, performing this analysis accurately was a challenging task because of the difficulty and quantity of calculations involved. This scenario began to change with the advent of the computer, which allowed the application of mathematical techniques, such as the Finite Element Method, to structural analysis, providing greater precision in the evaluations. Thus, based on the importance of these for civil construction, this work had as objective to provide the interpretation of the mechanical behavior of a deep beam subjected to static loads. For this, the software ABAQUS/CAE, student version 2018, was used to simulate the chosen example, detailing each step of the simulation process and how each of these can influence the results. Therefore, the computational simulation of the deep beam allowed to analyze the stress distribution along the element.Item Monitoramento físico-químico e ambiental dos solos do Complexo Industrial Portuário de Suape, Região Metropolitana do Recife, Pernambuco, Brasil(2019-05-22) Silva, Rodrigo Atanasio; Moraes, Alex Souza; http://lattes.cnpq.br/0440163845324480; http://lattes.cnpq.br/9853341999557777The present work refers to the study of the physical and chemical characteristics of the soils located in the areas of the Industrial and Port complex of Suape. They were obtained by carrying out a collection in 11 points spread within an area of 450 m², uniformly determined, to have a greater and better representation of the study area. The analyzes made in the laboratory served to determine the granulometry, consistency limits, color and main elements present in the different types of soils. The results obtained show a grouping of two large groups S8, S9, S3, S4, S2, S5 and S7, S11, S10, S6, S1 the first group presents soils with darker colors that are linked with the high amount of clay and the high value of IP. The second group has lighter colors and low amounts of clay, consequently, low IP values.Item 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/7949189322240161The 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.Item 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/1523292800241605The 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.Item Projeto estrutural de vigas-parede biapoiadas de concreto armado(2019-07-09) Couto, André Vinícius Melo; Silva, Jordlly Reydson de Barros; http://lattes.cnpq.br/4382584044561547; http://lattes.cnpq.br/4544033112109443The purpose of this work is to present the main fundamentals of single-span deep beams structural design, and analyze these elements through the Finite Element Method (FEM), using ABAQUS/CAE software, student version. During the study, a design procedure is discussed, which is implemented in the Smath Studio software. A discussion is also made about the FEM modeling procedure, such as the deep beam information implementation, such as material, supports and applied loads. Thus, for a problem present in the literature, the support tensions, provided by the software are compared, verifying the proximity of the answers obtained. Finally, a parameter study of the problem is made, through the Smath Studio routine, observing the influence of geometric parameters and loads on the behavior of the structure.Item A influência da gestão de pessoas no clima organizacional na Engenharia Civil: um estudo de caso aplicado a uma secretaria de obras públicas(2019-07-10) Monteiro, Gustavo José Rodrigues; Bento, Kaique Dias; http://lattes.cnpq.br/0159181694024505; http://lattes.cnpq.br/2946937082272919This article presents the main conclusions of an exploratory investigation, which has the purpose of evaluating a civil engineering company, more precisely the Public Works Department of Cabo de Santo Agostinho, regarding the management of people and whether it collaborates for the climate organizational structure. This research emphasizes the following aspects: Human Resource Management (HRM) policies and practices, processes of motivation, communication and leadership. The tool used to collect the data was a questionnaire containing 33 questions, encompassing all the variables of the research. The results were obtained from a non-probabilistic sample of 23 respondents. The collected data indicate that the policies and practices of people management are still new: There are difficulties of communication between hierarchical levels. The motivational level of the respondents is often low, since they feel undervalued, and the policies and HRM practices fail to ensure an organizational climate that meets the needs of the secretariat staff.Item Estudo da vulnerabilidade ambiental da barragem de Tapacurá pelo aporte natural do solo, Zona da Mata norte de Pernambuco, Brasil(2019-07-10) Lima, Nívea Ramos de; Moraes, Alex Souza; http://lattes.cnpq.br/0440163845324480; http://lattes.cnpq.br/5045118226452812Aprocess of use and occupation of the soils of hydrographic basins, it generates consequences as the increment of materials for the interior of the dam, thereby it is necessary to establish references about the current stage of contamination regarding the quality of the Sediments inside the Tapacurá Dam, which monitoring will allow a more systemic view of the area, regarding the excess or scarcity of some chemical elements, and serve as a geochemical and environmental study on the quality of the sediments present in this basin, aiming the construction of the EIA / RIME. The sediment samples were collected using a VAN VEEN dredger at predetermined points and destined to the laboratory, where the samples were prepared to follow for chemical analysis of the metals present in the sediments. As a first result, from the depths measured at each point, the map of the bathymetry of the Tapacurá basin was made. The toxicity of soil and sediment samples from the surrounding area of the dam was calculated from bibliographies serving as reference about the contribution of the elements to the basin. Finally, from the Enrichment Factor (EF) that was calculated using the Iron as normalizer element, it indicated that there is enrichment of Cadmium in all collected points distributed inside and outside the basin. However there are similarities between the values, it is not possible to confirm the origin of the change, making it necessary future studies that could recognize the nature of this element.Item Influência de fatores antrópicos na qualidade das águas subterrâneas da comunidade de Itapuama, Cabo de Santo Agostinho - PE(2019-07-11) Silva, Anderson José da; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/0895425089026343Item Influência da resistência característica (fck) na taxa de armadura em lajes nervuradas de concreto armado sob diferentes configurações de apoio para os concretos do grupo I e II de resistência, segundo a NBR 6118 (ABNT, 2014)(2019-07-12) Amorim Júnior, Laelson de Andrade; Melo, Weslley Imperiano Gomes de; http://lattes.cnpq.br/4789771132461158; http://lattes.cnpq.br/7943300714310248Ribbed slabs are being widely used in civil construction because they allow for large spans with low reinforcement rate, low concrete consumption and lower own weight, compared to massive type slabs, thus allowing execution of slender structures and consequently more economical. In addition to being easy to perform, it can be performed on site or through precast material and in various types of buildings, from homes to large hospitals and malls. Thus, the present work aims to verify influence of (fck) on the reinforcement rate in reinforced concrete ribbed slabs under different support configurations for strength groups I and II concretes, according to NBR 6118 (ABNT, 2014 ), through case study and elaboration of sizing routines based on the current literature. It can be observed that, for proposed case study, the increase of the (fck) had no great influence on reduction of the reinforcement rate, with only a 8.4% decrease in steel section, generating a cost reduction of 34% in its consumption, while the concrete had a significant increase of 190% in her cost. However, such an analysis was made only for ordinary residential buildings with small spans and small loads, so for spans and loading of special works such as bridges, nothing can be afirm.Item 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/6721685438361084One 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.Item Análise técnica de blocos cerâmicos de diferentes fabricantes comercializados na cidade do Cabo de Santo Agostinho de acordo com a norma NBR15270:2017(2019-07-12) Silva, Darliane Maria da; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/1329373862669135Item 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/1589879584642925Brazil 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.Item Caracterização físico-química e avaliação da qualidade das águas subterrâneas em poços da comunidade de Itapuama, Cabo de Santo Agostinho/PE(2019-12-11) Duarte, Wiliane Roberta da Silva; Silva, Robson José; http://lattes.cnpq.br/7515677435963888The 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.Item Influência da adubação com lodo do tratamento de esgoto doméstico no cultivo de feijão e milho(2021-03-01) Lyra, Gabriel Rigaud Figueirôa; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/3958782513733383In the biological stage of sewage treatment, part of the organic matter degraded by microorganisms is converted into biomass, which constitutes the biological sludge or secondary sludge. Currently, the most used alternative for final disposal of sludge in Brazil is sending it to landfill, due to the low operational cost involved. However, this technique does not include the nutritive and/or energetic potential of the sludge. That said, this study evaluated the use of sludge from domestic sewage treatment in the cultivation of cowpea bean seedlings (Vigna unguiculata (L.) Walp., Cultivar IPA 206) and corn (BRS Gorotuba), compared to the use of chemical fertilizers. The experimente for each culture was conducted in a greenhouse and set up in a completely randomized, with 4 treatments and 3 repetitions, using pots containing 10 kg of soil. The two cultivations were carried out in parallel. The 4 treatments applied were: without fertilization, chemical fertilizer (NPK), lime sludge and composted sludge (T0, T1, T2 and T3, respectively). Among the performance parameters analyzed, in both crops, T1, T2 and T3 treatments presented plants with equivalent physical aspects (plant height and stem diameter). With regard to beans, the treatment T3 stood out for the amount of pods per plant, being about 125% higher than others, and for the higher performance in the weight of 100 beans (29.67g). For corn, treatments T1, T2 and T3 achieved equivalent performance. However, T3 obtained the highest numerical averages in all parameters of this cultivation. Finally, it was observed that the treatment with the greatest influence, in both crops, was T3, reaffirming the great potential of composted sludgeItem Impactos da aplicação da metodologia BIM no planejamento e gerenciamento de empreendimentos do mercado AEC(2021-03-02) Meireles, Hygor Alves; Galvão, Simone Perruci; Ferreira Júnior, José Temístocles; http://lattes.cnpq.br/6415276115481076; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/4436024273659412BIM is a methodology that aims to collaboratively manage data in the architecture, engineering and construction sector, providing agility and reliability in the planning and operation phases of projects. Using processes based only on 2D technology, however, slows down the application of the best modeling and data management methods in this industry, often generating disagreement between agents involved in the project. Therefore, this study evaluates, through bibliographic review, the evolution of BIM’s methodology and the impacts resulting from its application in the planning and management of works. Data related to its development over the years, intrinsic characteristics, norms and legislation in force, as well as its influence on trends in the construction sector, were highlighted. For the literature analysis, books, articles and dissertations on the theme, produced between the years 2005 and 2020, were chosen, taking the number of citations as the selection criterion. It was observed that the main consequences regarding the application of BIM are: increase of workloads and financial contributions during implementation, reduction of rework and decrease in the project’s overall costs. The regular creation of rules and decrees on BIM demonstrates the existence of a trend of incentives for its adoption, aiming to add more quality to processes and, consequently, products.Item Otimização da malha de elementos finitos via software Ansys em núcleo C contraventado por lintéis(2021-03-04) Luz, Pedro Vítor Carvalho de Alencar; Mello, Weslley Imperiano Gomes de; http://lattes.cnpq.br/4789771132461158The modeling of structures via Finite Elements is quite usual nowadays, in view of its importance, this research was developed in order to provide subsidies to the modeling of reinforced concrete columns in thin walls of C cores braced by horizontal lintels in X and Z over the modeling possibilities through the commercial software Ansys. This paper presents the initial procedures necessary for the insertion of the geometry in the program platform and a comparison between the 3 types of existing meshes, Hexahedral, Tetrahedral and Prismatic, demonstrating their respective convergences, through data and analysis in the specified cases, exhibiting an accuracy of 96.25% in the 1st Vibration Mode of the column with horizontal lintels, an error notwithstanding 5% in the column with lintels arranged in X and an error less than 2% in the column with lintels arranged in Z.Item 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/2234155499243922It 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.Item Gestão ágil na construção civil: uma abordagem propositiva dos fatores de incremento em face à gestão tradicional(2021-03-05) Carvalho, Alan de Oliveira; Véras, Juliana Claudino; http://lattes.cnpq.br/8199104094050794; http://lattes.cnpq.br/9428820693597800The new industrial configurations in the most diverse fields of activity generate an extremely competitive environment, with difficult market scalability and increasing levels of demand from all parties involved in the execution of projects. Based on this statement, the search for new techniques to manage processes and projects gains particular relevance. The aim of the work presented here is to study the applicability of agile project management frameworks in the scope of civil construction by searching for possible increment factors agile project management in this specific branch of industry. Significant differences were identified between both industrial axes, especially in the management of the scope of the projects and in the preparation of their budgets. It was concluded that the applicability of agile management methodologies in civil engineering corporations, due to the very traits of this field of activity, is quite challenging. However, the set of values and approaches derived from such frameworks is highly recommended.Item 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/0232118019455098This 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.Item Gestão de resíduo sólido orgânico residencial em período de pandemia COVID-19(2021-07-22) Cruz, Ana Vitória de Souza; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/1049768443014317In front of the great increase in the generation of urban solid waste, recurrent of the disordered population growth, a composting is taken as an alternative for the treatment of the organic waste fraction. In this context, the objective of this research was to evaluate a domestic composting of solid waste from a residence, using the compost produced in the cultivation of collard greens seedlings and employing domestic composting and the practice of horticulture as a sustainable and productive activity, which induces physical and mental well-being in a pandemic period. The composting process lasted 120 days and was carried out in a designed mini composter. The organic compost produced was used to obtain seedlings of two collard greens species. The sowing was carried out in a tray with fifteen cells, set up in a completely randomized design, with five treatments and three replications. The applied treatments, T0, T1, T2, T3 and T4,corresponded, respectively, to 100% soil; 75% soil and 25% fertilizer; 50% soil and 50% fertilizer; 25% soil and 75% fertilizer and 100% fertilizer. They were avalueted: germination time, leaf length, leaf width, number of leaves, seedling height, root length and stem diameter. Treatments T2, T3 and T4 showed the best performances, with treatment T2 being the one with the best results for Brassica oleracea var. Costata and treatment T3 for Brassica oleracea var. Acephala. In addition, the study was assessed as adequate by the process participants, as it aroused interest, sustainable learning and productive routines, directly influencing the maintenance of well-being during pandemic period
