摘要

摘要: 利用方钢管配筋混凝土柱耐火极限的理论计算方法,对标准升温曲线升温及火灾有效荷载作用下,截面尺寸、构件长细比、截面含钢率、材料强度、荷载偏心率以及钢筋配筋率和钢筋强度对方钢管配筋混凝土柱耐火极限的影响进行分析。并在此基础上,提出按规范ISO-834和《建筑构件耐火试验方法》(GB9978-88)规定的标准升温曲线升温作用下,钢管配筋混凝土柱耐火极限的实用计算方法,计算结果与数值计算和试验结果均吻合较好。

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.
