Item Desenvolvimento de ferramenta computacional para o dimensionamento de blocos de ancoragem para tubulações sob pressão(2021-12-10) Medeiros, Khrys Kathyllen da Silva de; Silva, Jordlly Reydson de Barros; http://lattes.cnpq.br/4382584044561547; http://lattes.cnpq.br/5605761011467421Thrust blocks for pressurized pipelines are concrete blocks designed to resist the applied forces, mainly due to hydraulic thrust. In many situations, a thrust block is required to ensure the safety of the pipeline, therefore, it is necessary the verifications are carried out correctly to prove those elements’ stability and efficiency. In order to develop a computational tool to help in the thrust elements design and safety verification for pressurized pipelines, a computational software named ProBlocos was developed. The tool interface is divided into three main areas: input data, result report and thrust block sketch. Real blocks from academic research were used to carry out tests and check the results obtained by the created software. The results showed that the developed program is low-cost, simple and effective to aid in the development of pressure pipeline projects. Thereby, the proposed work can be used by engineering professionals and students, regardless of the user's familiarity with the computer language used.Item Produção de concretos com resíduos de poliuretano triturado em substituição ao agregado miúdo(2021-12-08) Pereira, Wesley Batista; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/7022069132421368The reuse of potential materials that would otherwise be sent to landfills or stored in incorrect locations, contributing to the pollution of water courses and influencing the sewage system of cities and the most varied damages to the environment and the population, is a reality each more current. Among these materials, the polyurethane polymer (PU) stands out in its many variations, where its reintroduction into the production chain brings socio-environmental advantages. This article presents a comparative analysis between a mix of conventional concrete and concretes with partial replacements of fine aggregate by crushed expanded polyurethane waste, from refrigerator scrap, in 5% and 10% contents, replaced in relation to the volume of the sand, this procedure was also performed for a mix with the addition of silica fume. Two pilot traces were developed, one with silica (CS) and one without silica (SS). The properties of the concrete produced were evaluated through the slump test of the cone trunk (NBR 16889: 2020), analysis of compressive strength (NBR 5739: 2018), tensile strength by diametrical compression (NBR 7222:2011), mass specific and water absorption (NBR 9778:2005). The results obtained from this study demonstrate that the increase in the amount of PU foam in concrete reduced significantly the specific mass and reduced the mechanical strength of the part. It is noteworthy that the use of silica fume can be a differential in the production of concrete with recycled aggregates such as expanded PU foam, so that the resistances are maintained.Item 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/2300010878356438After 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.Item Projeto de reuso de água pluvial em habitação popular para fins não potáveis(2019-12-12) Cruz, Ana Vitória de Souza; Silva, Robson José; http://lattes.cnpq.br/7515677435963888; http://lattes.cnpq.br/1049768443014317Strong population growth and urbanization have led to increased drinking water consumption. This factor, coupled with irresponsible use and pollution of water sources, has contributed to a considerable water crisis. Brazil is a privileged country, as it has 12% of the world's freshwater, but due to poor distribution, there are regions of the country where water availability is low, such as the Northeast of Brazil that faces severe scarcity crises most of the year. Therefore, the search for sustainable policies that provide solutions to this problem and at the same time make the population aware of the importance of conscious use of water is necessary. Within this context, the reuse of rainwater becomes a viable alternative, easily applied, which provides the preservation of the environment. Therefore, the present work elaborated a popular housing project in Recife based on the city's Master Plan and designed a Rainwater harvesting System for this dwelling, according to NBR 10844 (1989). In the project, the rainwater was captured only by water from the roof, which enough to meet the house reuse needs, as the city has a high rate of rainfall. The materials used in the installation of the collection system were low cost and simple to apply, where the implementation project presented a much lower cost than the total value of residential construction, besides representing an excellent alternative for environmental awareness and treated water savingItem Estudo comparativo entre técnicas de impermeabilização em talude do município de Jaboatão dos Guararapes/PE: lona plástica x gel polímero(2021-03-03) Santana, Bruna Candida de Lima; Borgatto, André Vinicius Azevedo; http://lattes.cnpq.br/4203791139862449; http://lattes.cnpq.br/0334928310277179Slopes are natural geological formations characterized mainly by large slopes over massifs of soil or rock. In this way, landslides in areas of occupied slopes usually occur in slopes of cut, embankments and natural slopes aggravated by the disordered occupation of buildings and human action. Therefore, it is necessary to increasingly expand the study of solutions for greater stabilization of embankments, thus mitigating the risk associated with the most vulnerable population and exposed to unsafe conditions of habitability. In order to carry out a qualitative study between the waterproofing techniques based on the application of plastic canvas and chemical product based on acrylic polymer gel on the slope of the municipality of Jaboatão dos Guararapes / PE, by comparing aspects such as durability, environmental impact, maintenance, useful life of the structure, cost and stages of execution of the permeability improvement techniques was able to determine the technique of greatest acceptance by the local population and with the greatest benefit / cost.Item Avaliação das propriedades mecânicas de um concreto não estrutural utilizando agregado de PET em substituição ao agregado miúdo(2019-02-01) Meireles, Hygor Alves; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/4436024273659412Item Estudo de viabilidade de um muro residencial sustentável para aproveitamento de água da chuva(2017-09-01) Brito, André William Barbosa; Millán, Miguel Alejandro Zorro; http://lattes.cnpq.br/9473835336187621; http://lattes.cnpq.br/1589879584642925Brazil is a privileged country in the world due to its hydrographic wealth. However, there are regions of the country where rates of water shortage are alarming. One example is the Brazilian northeast, which faces a water crisis during most of the year. In addition, the consumption of drinking water for activities that do not require this water has grown. In this context, the main objective of this research is to analyze the feasibility of installing a sustainable residential wall for the use of rainwater in the municipality of Cabo de Santo Agostinho, as a solution for the adequate use of drinking water and a way of minimizing water shortage. For the development of this study, rainfall data were obtained from the city and the metropolitan area of Recife and dimensioned horizontal gutters and ducts according to NBR 10844 (1989). In addition, a model residence was chosen according to the socioeconomic aspects of the municipality, the costs and ways of obtaining materials from the wall were analyzed, as well as its efficiency in relation to the rainfall data of the region where the house is located during the months of the year. It is demonstrated that the sustainable wall for the use of rainwater can be feasible to be applied in Cabo de Santo Agostinho, since it presents low cost compared to other forms of vertical reservoirs, good efficiency and simplicity in its installation, providing a great shape and adequate use of rainwater.Item 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/7949189322240161The 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.Item Gestão de resíduos de construção e demolição aplicada no município do Recife(2017-08-08) Santana, Vitor Carneiro de; Galvão, Simone Perruci; http://lattes.cnpq.br/1523292800241605; http://lattes.cnpq.br/6721685438361084Civil construction is one of the sectors with the largest participation in the Brazilian economy. However, the high dynamism of this activity leads to an increase in the generation of construction and demolition waste (RCD), promoting greater environmental impacts if managed improperly. For this reason, it becomes relevant to know the main measures adopted by civil construction companies and by the municipal bodies competent for the prevention and final destination of these wastes. This study presents an exposition of the main management policies of construction and demolition waste adopted by the public management of the city of Recife and in five works located in the municipality. In order to do this, we carried out on-site visits to buildings and to the Urban Maintenance and Cleaning Company (EMLURB), in order to obtain data pertinent to the research. The data were collected through interviews, using an electronic questionnaire associated to the virtual platform Google Forms as an instrument. The information acquired was verified according to the guidelines of CONAMA Resolution Nº 307/2002. Thus, it was verified the existence of municipal legislations on the adequate destination of RCD that assign responsibilities to the companies and the municipal organs of urban cleaning. Regarding waste management, it was verified that the type of disposal most adopted among the companies of this study was the collection and final disposal of private landfills, while one of the companies adopts the waste recycling service for reuse in the work.Item 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/0895425089026343The 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.
