Relationships between fire proofing material amount and seismic structural resistant margins for steel buildings
Abstract eng: In case when fire resistance of a steel frame is verified in seismic regions, it is important to understand effect of seismic design on fire resistant design, to improve both seismic and fire resistant performance. The main purpose of this paper is to clarify relationships between an input amount of fire proofing material and a seismic structural resistant margin, which is given by a quotient of horizontal load-bearing capacity divided by required horizontal load-bearing capacity of the steel frame. To estimate minimum value of the required fire proofing material amount, Genetic Algorithm (GA) analyses are conducted. From minute investigation of the parametric numerical results, it was clarified that the fire proofing material amount can be reduced in the case of steel frame with the large seismic structural resistant margin, because the redundant seismic frames have the high collapse temperatures and large thermal capacity of the large cross-sectional area members.
