| 摘 要： | 本文探讨用软化桁架模型分析钢筋混凝土矩形截面复合受扭构件。将其内力和变形关系分成开裂前和开裂后两阶段,开裂前按弹性工作状态计;开裂后用不等厚薄壁箱形截面代替矩形截面,用折减剪力的办法考虑核心混凝土的抗剪作用,使之与抗扭的桁架模型相协调。文未据此编制了矩形截面复合受扭构件全过程分析程序,并将计算结果与实测值作了比较.

| Abstract: | The softening variable-angle truss model theory is applied to analyize rectangular RC combined torsional members in this paper. Their torque-twist curves are seperated into two segments: which are calculated according to elastic theory before cracking, and after cracking the softening variable-angle truss model is applied to analyze their equivalent thin-wall box sections. Program to predict torque- twist curves of rectangular RC combined torsional members is drawn up and the calculating results are compared with test ones . |
