Estudo comparativo de diferentes métodos de proteção estrutural passiva contra incêndio em edifício de oito pavimentos em aço localizado em Maceió

Abstract

The present work has studied the financial, technical, and logistical feasibility of the following passive fire protection materials: non-structural concrete enclosure, masonry in ceramic blocks, masonry in concrete blocks, gypsum boards, rock wool boards, ceramic blanket, vermiculite projected mortar, and intumescent paint, aiming to define the most accessible fire protection coating material. The comparison is made through the pricing and application data such as productivity, area and stockage of the protection methods for a hypothetical base building, assumed to be in the city of Maceió. From the BIM modeling of the structure, quantities were extracted, which were later budgeted based on data from SINAPI, ORSE, and Cype, considering the material, labor, transportation, and real estate devaluation through the loss of useful area in the building. In the end, based on comparisons of price, weight, occupied storage space, and execution time, it was found that, for the case studied, the vermiculite projected mortar would be the best solution.
