Análise de parede de concreto armado sob a ação do fogo

Abstract

This study aims to analyze and compare the behavior of a reinforced concrete wall under fire conditions, as well as to suggest alternatives that may improve the performance of the structure under study. This type of construction system is widely used in engineering, with common applications including material storage tanks and structural walls. In both cases, it is essential that the structure withstands a certain amount of time under fire exposure to ensure the safety of those involved. Therefore, through a comparative analysis with a laboratory experiment, this work examined the behavior of a reinforced concrete wall under fire exposure using the ANSYS computational software. Additionally, analyses were conducted to determine whether variations in the compressive strength of concrete and boundary conditions influence the fire response in reinforced concrete walls. Based on the results obtained, it was found that increasing the compressive strength modify the stress and strain values generated by the fire.
