摘    要:通过对7个钢管混凝土柱的耐火试验,研究钢管混凝土柱在标准升温曲线下的力学性能和耐火极限.试验研究结果表明,由于钢管和混凝土的共同工作,且核心混凝土具有较好的吸热性能,从而使钢管混凝土柱具有较好的耐火性能,在柱子外围只需进行适当的防火涂料保护,即可达到<高层民用建筑设计防火规范(GB50045-95)>对柱结构所要求的耐火极限.本文的研究成果可为钢管混凝土工程进行防火设计时提供参考.

关 键 词:钢管混凝土    力学性能  耐火极限

Abstract:Seve large-scale conrete filled steel tubular columns were tested for the fire resistance followed the Standard Fire Curve.The behavor and the limitation of fire resistance of columns are studied. The experimental results show that the concrete filledseel tubular columns have excellent behavior and higher fire resistance because of the interaction bo the steel tube and itscoure concrete and the good heat absorption in the core are. The columms with proper fire retardant coating can be satisfiedfor the design fire resistance that is the requirement by the Chinese code named < GB 50045-95 Code for Fire Protection ofHigh Pise Buildiny >. Some valuable conlusions are appeiated for reference.
Keywords:concrete filled steel tubes  column  behavior  fire resistance
