摘　　要：把钢管混凝土当作一种组合材料，首次从理论上用有限元法分析了钢管初应力对钢管混凝土压弯和压弯扭构件工作性能的影响。同时，为了工程应用的方便，推导出了有初应力值时钢管混凝土压弯、庄弯扭构件承载力相关方程。为了验证理论分析的正确，完成了一批系统的对比试验。ln this paper, concrete filled steel tube (CFSF) is considered as a composite material . Baseed on the finite element metbod, it is the first time to analyse the behavior effect for CFST compression - bending compression-beading-torsion members on the condition of having initial stress in steel tube. Besides, the practice interaction equations for CFST metnbers are deduced for the sake of convenient use in actual structures . Finally , in or der to prove the theoretical results, a series of systematical tests of CFST members on the condition of baving initial stress in steel tube have been done.
