Title: Software para dimensionamento à flexão de vigas de concreto protendido com armadura ativa não aderente Abstract: This study presents the development of software for the flexural design of rectangular prestressed concrete beams post-tensioned with unbonded tendons. The computational tool evaluates prestress losses, including both immediate and time-dependent losses, as well as their effects on serviceability and ultimate limit state verifications. The software was implemented in C++ based on the procedures established by ABNT NBR 6118:2026 and on the calculation report prepared by civil engineer Pedro Henrique Cabral, which was adopted as a reference for validating the results. Initially, the theoretical principles of prestressed concrete and the main mechanisms responsible for prestress losses are reviewed. Subsequently, the analytical models and calculation procedures used to determine immediate and time-dependent losses are presented. The serviceability and ultimate limit state verifications are then performed. As a result, this study systematizes a calculation procedure for the flexural design of beams with unbonded prestressing and provides a computational tool capable of automating the calculation stages, facilitating the analysis of results, and supporting the comparison of different design conditions. The software is intended for use by engineers, structural designers, and students in the field of concrete structures.

Title: Sistematização do cálculo da capacidade de carga e previsão de recalque em fundações Abstract: The design of deep foundations is essential to ensure the safety and structural performance of buildings, with piles serving as fundamental elements in transferring loads to the soil. In this work, an automated calculation spreadsheet was developed to evaluate the loadbearing capacity and settlement of piles, using exclusively field data obtained through the Standard Penetration Test (SPT). Some of the main well-established methods from the literature were integrated, with the aim of creating a reliable and user-friendly tool. The proposed spreadsheet enables calculations to be carried out quickly and in a standardized manner, minimizing errors and facilitating decision-making during the design phase. It is expected that this tool will contribute to everyday practice in the development of foundation projects, promoting greater efficiency and safety.

Title: Análise numérica da inserção de enrijecedores de alma em terças de aço formado a frio Abstract: Cold-formed steel profiles constitute an efficient and versatile structural solution in civil engineering, standing out for their high strength-to-weight ratio, dimensional precision, and wide applicability in modern construction systems. This study addresses the analysis of the structural behavior of cold-formed steel profiles, with emphasis on the influence of web stiffeners and slenderness variation on the structural performance of these elements. The research was developed through numerical modeling using the Finite Element Method, with the aid of Abaqus software, enabling the evaluation of the critical moment and the instability modes associated with the analyzed profiles. The results indicate that the use of stiffeners can significantly contribute to increasing the load-bearing capacity of the profiles, especially in situations where local buckling predominates. However, it was observed that, in certain cases, the insertion of these elements does not result in structural gains, particularly when the behavior is governed by global instabilities. Thus, the study highlights the importance of a careful analysis of geometric and mechanical parameters in the design of cold-formed steel profiles, contributing to the development of more efficient, safe, and economically viable solutions in structural engineering.
