Procedure for decreasing the required time for fire resistance of the multistory buildings

Abstract: ResumoThe Brazilian standard ABNT NBR 15200: 2012 details a procedure for decreasing the required time of fire resistance in buildings with good fire safety characteristics. It called equivalent time method. This name can confuse the less habituated to the fire safety area, because the Brazilian procedure is not equal to the original equivalent time method, European. The purpose of this paper is to discuss the equivalent time method, to detail the origins of the Brazilian method and present their limitations n… Show more

“…It is important to note that although IT 8 [4] tabular method indicates a minimum standard-fire resistance time of 30 min, it is possible to adopt lower times for small buildings with low fire load by utilizing the equivalent time method. This method is detailed in ABNT NBR 15200 [5], ABNT NBR 14323 [6] and IT 8 [4], and commented by Silva et al [7]. This present paper analyzed the simplifying hypotheses adopted in Romagnoli and Silva [2].…”
