Redistribuição de esforços verticais em uma edificação frente à possibilidade de colapso progressivo

Abstract

rogressive collapse is a phenomenon of structural failure, which has already caused the total or partial collapse of several buildings in the world. Since the 1950s, this has been a topic studied in other countries, which already have measures for the prevention of progressive collapse described in their regulatory standards. In Brazil, this topic started to be debated recently, with an absence of adequate normative information and more in-depth studies on the topic. In this work, a brief study was carried out on the progressive collapse, presenting its definition, type, main causes, cases occurred in buildings and preventive measures. A fictitious building was modeled in the TQS software according to the Brazilian standard NBR 6118 (2014), modifications were made to the structure, such as the removal of pillars, to analyze the behavior of the structure in the face of the loss of support elements.
