摘　　要：论述了钢管初始应力对钢管混凝土构件工作性能影响的主要原因，及对这一问题进行研究的必要性。分析了对轴压、压弯和压弯扭剪构件承载力的影响，提出了验算公式和限制钢管初始应力比的建议。The main rcason of influence of initial stress in steel tube on the behaviours of CFST members is explained in this paper. The necessity of research on this object is expounded also. The influences on load carrying capacities of axial compression members, compression with bending members, as well as compression - bending with torsion and shear members are analysed. Finally, the calculation formula and the limit initial stress ratio for axial compression members are suggested by authors.
