| 摘 要： | 对4榀单层单跨的圆形钢管混凝土柱-钢筋混凝土梁带楼板组合框架在火灾下的温度场进行试验,研究组合框架中的钢管混凝土柱和钢筋混凝土梁温度场分布的特点,并对比不同防火涂料厚度、不同梁高等情况下的温度-受火时间关系曲线。最后采用有限元方法计算了组合框架的温度场,结果表明,计算结果和试验结果总体上较为吻合。

| Abstract: | Experimental studies on four concrete-filled steel tubular column to reinforced concrete beam frames under fire have been carried out to study the temperature distributions inside the structures.The effects of column fire protection thickness and the height of the RC beams on the temperature versus fire exposure time curves are analyzed.A finite element model is used to calculate the temperature fields,and it is found that the calculated results show generally good agreements with those of the tests. |
