Abstract

In this study, the authors developed software named Sonar to analyze the progressive collapse of structural elements. This software is capable of assessing the level of damage to each structural component and automatically updating the structural model for subsequent analyses. The software features a user-friendly interface, intuitive graphics, easy input of parameters, and presents computational results in 2D graphics. Through the use of the developed software, damaged structures were analyzed and studied to conclude that considering the progressive collapse of elements based on the plastic damage index serves as a basis for investigating specific design problems to propose more optimal design solutions.
