摘要 把钢管混凝土当作一种组合材料,从理论上首次用有限元法分析了钢管初应力对钢管混凝土抗压组合力学性能指标和轴压构件承载力的影响。为了验证理论结果,还完成了一批有和无初应力的轴压构件对比试验。 In this paper,concrete filled steel tube (CFST) is considered as a composited material. Based on the finite element method, it is the first time to analyze the effects of composite mechanical performance parameters and ultimate load for CFST compression members on the condition of having initial stress in the steel tube.In order to prove the theoretical results,a series of systematical tests of CFST compression members on the condition of having initial stress in the steel tube have been done.
