| 摘 要： | 在合理的确定了火灾情况下钢管混凝土表面温度的基础上，利用有限元法计算方截面钢管混凝土在高温作用下的温度场，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）及不同钢管尺寸对方截面钢管混凝土温度场的影响，从而为进一步研究钢管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, FiniteElement method is applied to calculate the temperature field of concrete filled square steel tubes underhigh temperature, and the calculated results fit with those of test very satisfactorily. And the effect ofdifferent fire protect layers and different dimension of steel tubes on the temperature field of concretefilled square steel tubes under high temperature is considered. The work of this paper makes it possibleto study the fire resistance of concrete filled square steel tubular structures. |
