钢筋混凝土受扭构件计算模型的修正与研究

钢筋混凝土受扭构件合理的计算模型需要一套准确的材料本构关系方程,考虑了钢筋混凝土受扭构件开裂后受拉混凝土的作用,分析了其对受扭构件承载力和变形的影响。对计算模型中的受拉混凝土和钢筋的本构关系方程作了改进,并对受扭构件承载力和变形做了计算,理论结果和试验结果吻合较好。

Modification and Study of the Calculation Models for Reinforced Concrete Torsion Members

A rational calculation model in reinforced concrete torsion members requires a set of constitutive laws for materials. This paper considers the tensile concrete in reinforced concrete torsion members after cracking, and analyzes its effect on the capacity and deformation of the foregoing members. The constitutive laws of tensile concrete and bar in calculation model are modified, and the capacity and deformation are calculated. Results show that theoretical data conform well to experimental results.
