| 摘 要： | 为了探讨剪力墙分布形式与布置数量对于框架剪力墙抗震性能的影响,拟采用ANSYS有限元软件对某24层高层框架剪力墙结构进行数值模拟分析。设置2种沿不同方向的地震波,作用于3种不同的剪力墙分布形式的结构上,并对其结构频率及层间位移进行对比分析。结果表明,随地震波的作用方向不同,相同的剪力墙布置形式对结构的抗震性能存在一定的影响;在同一地震波作用下,采取合理的剪力墙布置形式并适当增多剪力墙数量可以提高高层框架剪力墙结构的抗震性能。

| Abstract: | In order to discuss the influence of shear wall distribution and arrangement quantity on the seismic performance of frame shear walls,this paper intends to use ANSYS finite element software to carry out numerical simulation analysis on a 24-story high-rise frame shear wall structure.Two kinds of seismic waves along different directions are set up to act on the structures with three different shear wall distribution forms,and the structural frequency and interlayer displacement are compared and analyzed.The results show that the same shear wall arrangement has certain influence on the seismic performance of the structure with the different action directions of seismic waves.Under the action of the same seismic wave,the seismic performance of high-rise frame shear wall structures can be improved by adopting reasonable shear wall layout and appropriately increasing the number of shear walls. |
