Análise comportamental de lajes de concreto armado em situação de incêndio

Abstract

The studies on the influence of fire on materials has been carried out for more than 150 years, throughout that time, with the ascension of civil engineering, it was possible to discover new technologies and solutions that guarantee a greater structural safety so that buildings, when subjected to fires, do not collapse. Thus, it is possible to understand the importance of the relevant points that result in beneficial discussions and therefore end up being useful to the progress related to this subject. In the mid-1970s, fire prevention and firefighting institutions across the country have structured many regulations with the aim of reducing the number of fires in buildings. However, recent events in the country have made the structural safety of buildings subjected to fire become one of the priority factors in the design of structural elements. This study presents, besides the general and historical context, the case of a building properly designed for ABNT NBR 6118:2014 – Design of concrete structures, in order to verify if the building is designed according to ABNT NBR 15200:2012 – Design of concrete structures under fire influence – Procedure, recommendations.
