Survey of occurrences and proposal for verification of structural integrity after fire buildings in Cuiabá (MT)

Abstract

As a way to better understand the behavior of the incidence of fires in the metropolitan region of Cuiabá, more precisely in the historical center region, a compilation of cases that occurred in a period of 10 years, between January 2009 and December 2018 was made. After the occurrence of fire, many buildings continue to be used, thinking about it, the present work carried out an investigation on the structural conditions of the reinforced concrete of the buildings remaining from fire, observing it by means of non-destructive test of ultrasonic and sclerometry. The results obtained in filtering fire occurrence data are consistent with what was expected to be found in relation to the months with the highest incidence of fire cases with the dry season in the Cuiabá region. The ultrasonic test performed in this work proved to be an excellent way to ascertain the structural integrity of reinforced concrete elements in order to know the quality of the concrete internally and not further compromise the structure already damaged by the fire, as well as in the effective sclerometric test to determine the surface strength of the structural element.
