填充墙竖向不均匀布置对框架结构的抗震性能影响

Influence of Vertical Non-uniform Layout of Filling Wall on Seismic Behavior of Frame Structures

填充墙对框架结构的抗震性能影响比较大。目前,各国规范通常使用周期折减法,来探究填充墙对结构刚度的影响。然而,填充墙设置差异对结构抗震性能的影响研究还很少。文章针对填充墙框架结构进行Pushover分析,探究填充墙在竖直方向不均匀设置时对框架结构抗震性能的影响,所得结论可供工程设计参考。

Filling wall has a great influence on the seismic performance of frame structure. At present, the national norms generally use the cycle reduction method to analyze the impact of the filling wall on the stiffness of the frame structure. However, there are few studies on the effect of the filling wall on the seismic performance of the structure. In this paper, Modal and Pushover analysis were carried out to study the influence of vertical non-uniform layout of filling wall on seismic behavior of frame structures and the conclusions obtained can be used as reference for the engineering design.
