| 摘 要： | 依据基于损伤能释放率的混凝土弹塑性损伤本构模型，对一类新型钢筋混凝土双连梁短肢剪力墙进行了数值仿真．考察不同位移水平下应力分布变化以及典型位移时刻受拉与受剪损伤演化过程并与试验结果对比，发现仿真结果不仅揭示了双连梁短肢剪力墙结构受力全过程中非线性反应发展主线，而且从微观损伤层次再现了钢筋混凝土结构的非线性反应．

| Abstract: | In light of the damage energy release rate-based elastoplastic damage constitutive model for concrete,this paper has carried out the numerical simulation of a new-type short-pier shear wall specimen with twin coupling beams.In virtue of stress distributions at different displacement levels as well as the tensile and shear damage states at typical displacement levels,the current study has not only disclosed the complete structural responses,but also reproduced the nonlinear responses of reinforced concrete structures from damage evolution at the micro level. |
