| 摘 要： | 参照日本规范,推导了适用于我国钢管混凝土柱的抗火验算公式,并对本文公式和按常用参数回归得到的公式进行了比较,最后采用对某大厦钢管混凝土柱进行了火灾下的承载力验算.2004年出版的《矩形钢管混凝土结构技术规程》CECS159：2004,给出了矩形钢管混凝土抗火验算方法,但关于圆形钢管混凝土构件目前尚无相应的抗火计算方法.

| Abstract: | 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. |
