Abordagem computacional para o reforço de vigas com aberturas na alma

Abstract

The lack of compatibility between structural and complementary projects represents one of the most recurring challenges in civil engineering today. This lack of integration often leads to the need for adjustments during execution, such as the insertion of openings in reinforced concrete structural elements to allow the passage of pipes, a practice that can result in changes to the beam’s structural behavior and compromise the safety of the structure. In this context, the objective of this study was to develop a computational algorithm capable of automating the design of reinforcements in beams with web openings, aiming to streamline and standardize the process. The algorithm was implemented in the Visual Basic programming language and its validation was carried out through the modeling of ten beams with distinct characteristics, which were analyzed using the developed program (AUREA) and two commercial software tools, Eberick® and TQS®. The results obtained from the comparative analysis showed similarity between the solutions generated by AUREA and those presented by the other analyzed software, demonstrating its effectiveness in reinforcement design. It is concluded that the developed algorithm represents a viable and promising alternative for the automation of reinforcement design in reinforced concrete beams with web openings. Although it still requires minor calibration, the program successfully achieves the objective of this study by reducing analysis time and minimizing potential human errors, contributing to greater accuracy in interventions and enhanced structural safety.
