| 中文摘要: |
| 建立了由墙肢单元模型、连粱单元模型和连接单元模型组成的钢筋混凝土双肢剪力墙的静力弹塑性分析计算模型。墙肢单元采用以有限元为基础的宏模型；按是否出现对角线剪切破坏，分别建立短连粱计算模型和长连粱计算模型；为计及连粱与墙肢连接界面的相对位移，建立用复合弹簧模拟的连接单元计算模型；给出了确定模型参数的方法。对有关文献的短连粱和长连粱双肢剪力墙试件进行了静力弹塑性分析，分析结果与试验结果符合较好。 |
| 英文摘要: |
| A calculation model of reinforced concrete coupled shear wall for static elasto-plastic analysis is developed. The model is composed of wall panel element model, coupling beam element model and connecting element model. A macro-model based on finite element method is used to model wall panel elements. According to whether the diagonal shear failure occurs or not, short coupling beam model and long coupling beam model are developed respectively. To account the relative deformation between the coupling beam and the wall panel, the connecting element is modeled by a complex spring. The parameters of the model are provided. Static elasto-plastic analysis of tested coupled shear wall specimens with short coupling beams or long coupling beams are performed, and the analyfical results are in good agreement with the experimental results. |
