| 摘 要： | 钢筋混凝土受扭构件计算中,薄膜元理论计算模型需要一套准确的材料本构关系方程,本文考虑了钢筋混凝土受扭构件开裂后受拉混凝土的作用,并对计算模型中钢筋的本构关系方程做了改进,分析了其对受扭构件承载力和变形的影响,理论结果和试验结果吻合较好。

| Abstract: | In calculation of reinforced concrete torsion members,a set of constitutive laws for materials is required in membrane-element model.In this paper,the tensile concrete is considered in reinforced concrete torsion members after cracking,and the constitutive laws of bar in calculation model are modified,the effect of which plays on capacity and deformation of members is discussed,it is shown that theoretical results conforms well to experimental results. |
