Item Desenvolvimento de uma ferramenta computacional para a análise de membranas em concreto armado(2023-09-22) Medeiros, Khrys Kathyllen da Silva de; Silva, Jordlly Reydson de Barros; http://lattes.cnpq.br/4382584044561547; http://lattes.cnpq.br/5605761011467421In this work, the behavior of reinforced concrete membranes is studied using the Modified Compression Field Theory (MCFT) and Rotating-Angle Softened Truss Model (RA-STM), both based on the solution of non-linear equation systems formulated based on equilibrium equations, strains compatibility, and material constitutive models. Initially, the models were implemented in Python programming language, and the Mohr Compatibility Truss Model (MCTM) was used as the initial estimate for the solution. Subsequently, the computational code was tested through some examples, and the results obtained were compared with numerical solutions from the literature and experimental tests, thus verifying the effectiveness of the method. With this, it was concluded that both analysis models presented good results, but the MCFT technique was closer to reality since it considers the concrete tension stiffening, unlike RA-STM. The developed implementation is a simple, effective, and computationally low-cost approach for assisting in the analysis of reinforced concrete panels subjected to membrane forces. Additionally, a graphical user interface was developed, making it accessible to professionals and students in the field of Civil Engineering, regardless of their familiarity with the programming language used. Therefore, the tool becomes an affordable alternative in terms of design, as it easily allows testing various combinations of material properties to determine the most viable option without compromising productivity.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.
