摘　　要：本文利用变角度空间桁架理论，考虑开裂后砼的软化，对弯、剪、扭复合受力下的预应力砼构件，推导了复合受力全过程计算方法，并将理论计算值与试验结果进行了比较，符合程度良好．In this poper, based on the variable angle space truss model theory, and considering the softening of cracked concrete, a set of theoretical equations is developed These equations can be used to calculate the complete response of members under combined totsion,bending and shear. The comparisiono of theoretical prediCtions to the experimental tesults thews good agreement.
