Análisis numérico de vigas de hormigón armado sometido a cargas estáticas

Abstract

Abstract: Theoretical models for the design and analysis of existing reinforced concrete beams provide students with the tools to understand their behavior when subjected to different loads. However, his study process has become methodical and needs to be fully understood. In this sentence, the part of the experimental sentences is considered necessary to visualize and understand the different failure processes, which entails time and resources that are only available to some students or professionals interested in the theme. This document explains the step-by-step methodology to define a numerical model developed in the free software OpenSeesPy, which simulates a three-point test on a reinforced concrete beam. The results were validated through experimental tests of 12 specimens designed for four types of failure (ductile, brittle, balanced, and by shear); from the comparative analysis of results through force-displacement graphs, it was possible to show that the numerical model implemented conforms to the experimental values.
