摘要
利用有限元法计算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，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。
Finite element method is adopted to calculate the temperature field of concrete filled steel tubes under high temperature, the calculated results fit with those of tests satisfactorily The work in this paper make it possible for the further researches on the behaviors and fire resistance of concrete filled steel tubes
