| 摘 要： | 在合理地确定了火灾情况下钢管高强混凝土柱受火模型的基础上 ,利用有限元法计算钢管高强混凝土在火灾情况下的温度场。计算结果与试验结果吻合良好 ,并考虑了不同保护层厚度 (混凝土和防火涂料 )及不同直径对钢管混凝土温度场的影响 ,从而为进一步研究钢管高强混凝土的耐火极限和高温下的力学性能创造了条件

| Abstract: | On the basis of the reasonable definition of column′s surface temperature in fire, finite element method is applied to calculate the temperature field of high strength concrete filled steel tubes under high temperature,and the calculated results fit with those of test very satisfactorily.And the effect of different fire protect layers and different dimension of steel tubes on the temperature field of concrete filled steel tubes under high temperature is considered.The work of this paper make it possible to study the fire resistance of high strength concrete filled steel tubular structures. |
