摘要
提出了小扭弯比情况下箱形截面预应力混凝土构件在弯、剪、扭共同作用下的板－桁模型计算方法，按照力的平衡、变形协调及材料本构关系等，建立了相应的计算方程，并编制了全过程分析的电算程序。通过对试验资料的验证，符合情况良好。对预应力、箱形截面翼缘及构件力素比的影响进行了分析。
This paper presents the platetruss model calculating method of prestessed concrete member under combined bending. shear and torsion. The calculating formulas have been set up and computer programs have been compiled according to the conditions of equilibrium of forces. compatibility of deformations and constitutive relationship of materials. The computational results agree well with the test data. Furthermore, the influences of prestress. flange of box section and ratio of torsion and moment have been analyzed.
