考虑结构损伤的剪力墙单元力学模型
|
摘要
多垂直杆模型是一种较为理想的宏观墙单元模型,在该模型的基础上进行改进,考虑损伤对剪力墙单元结构的影响,建立考虑结构损伤的剪力墙多垂直杆单元力学模型。利用该力学模型编制相应程序,对4个两种不同边缘约束措施的叠合板式剪力墙和2个普通剪力墙进行非线性分析,计算结果与试验结果吻合良好,表明该方法是可靠的。
An effective macroscopic model,multi-vertical-line-element model has been used to nonlinear analysis for reinforced concrete shear wall structures by many researchers.Considering the shear wall damage,the model was improved.By use of the model,the corresponding model was compiled to compute four superimposed slab shear walls with edge restricted measures of two different forms and two general shear walls using static analysis.The calculating results of this model and the experimental phenomenon were in good agreement.The results showed that the method was reasonable and reliable.
