摘要

摘要: 在合理地确定了组成方钢管配筋混凝土的钢材和核心混凝土高温下的应力-应变关系模型基础上，建立了方钢管配筋混凝土柱耐火极限的理论计算模型，理论结果与以往国内外试验结果对比，两者吻合较好，可为方钢管配筋混凝土柱的防火设计提供参考。

Abstract: On the basis of deciding the stress-strain relations of steel, bars and core concrete of bar-reinforced concrete filled square steel tubes, a theoretical model for the analysis of fire resistance has been put forward.The model has been validated by testing results.There is a good agreement between the two.The method introduced in this paper may be a reference for fireproof design of this sort of column.
