Abstract

Used of the theoretical model for the analysis of fire resistance of bar-reinforced concrete filled square steel tubes,factors affecting the fire resistance,such as sectional dimension;slenderness ratio;steel ratio;strength of materials;eccentricity;bar-reinforced ratio and strength of bar-reinforcement,are analyzed.On the basis of that,fire resistance formula is proposed according to ISO-834 and GB 9978-88.
