摘要
提出了一种具备自复位能力的可更换墙脚部件,介绍了该部件的构造和受力机理.建立了带有该新型可更换墙脚部件的钢筋混凝土剪力墙的非线性数值计算模型,进行了剪力墙在低周反复加载下的受力性能分析,研究了墙脚部件中碟簧组的刚度和预压力对剪力墙抗震性能的影响.结果表明,带新型可更换墙脚部件的剪力墙具有良好的抗震性能,结构残余变形小,主体结构损伤低,可实现震后使用功能的快速恢复.
A new type of replaceable corner component with self-centering capability was proposed,and the details and the loading mechanism of the new component were introduced.Furthermoer,the numerical model of RC shear wall with the new replaceable corner components was established,and the seismic performance of shear walls was analyzed and the effect of stiffiness and preload of disc springs in components on the shear walls was studied.The results show that the shear wall with the new replaceable corner components has good seismic performance and the characteristics of low residual deformation and low damage,and the function of the shear wall structure can be quickly restored by replacing the replaceable components after earthquake.
