钢管混凝土耐火性能的研究钢管混凝土柱自1995年开始在我国出现，2004年国家设计规范《矩形钢管混凝土结构技术规程》颁布。规范中推荐了矩形截面钢管混凝土柱的抗火设计方法，而圆形截面钢管混凝土柱的抗火设计方法则未给出本文根据日本的设计方法，推导出一套圆形截面钢管混凝土框架柱抗火设计的修正方法，并与文献[1]进行了数值比较，用修正后的方法对上海某高层建筑的抗火能力进行了分析。
Researches about the fire resistance of CFT(connrete-filled steel tube) columns have been found in China since 1995.The national design code 'Technical specification for structures with concrete-filled rectangular steel tube members' was published in 2004.The fire-resistance design method about the CFT with rectangular section is recommended in the specification.No methods about fire resistance of CFT with circular section are recommended.According to the Japanese design method,a set of revised design method of fire resistance of CFT with circular section is derived in the paper.The numerical comparison of the method with the reference[1] is presented.The revised method is used for analysis of the fire resistance capacity of a tall building in Shanghai.
