摘要
为了更好地了解在水平内荷载作用下填充墙对框架结构抗震性能的影响,利用ANSYS有限元软件对其进行平面内荷载作用下非线性分析,分别建立纯框架和框架填充墙结构模型,计算了填充墙在平面内单调递增荷载作用下的承载力、刚度、位移、延性等参数的变化特征。计算结果表明,与框架有效连接的填充墙在平面内荷载作用下对主体结构产生有利影响,其承载力、刚度、延性比纯框架模型都有明显的增大。还研究了填充墙在水平低周反复荷载作用下对框架抗震性能的影响,并得到了相应的滞回曲线。
In order to better understand how the filler wall affects the seismic performance of frame work within the horizontal loads, nonlinear analysis of finite element software AN- SYS under in-plane loads is used. Pure frame and infill frame structure models are established to calculate the filler wall variation characteristics of parameters such as bearing ca- pacity, stiffness displacement and ductility under the in-plane increasing loads and receive the effects of filler wall under in-plane loads on seismic performance of frame structure. The calculations indicated that the filler wall which is validly connected to frame structure has favorable impacts on the main structure under in-plane loads and its bearing capacity, stiffness, ductility increased significantly than pure frame model. Moreover, the influence of filler wall on the seismic performance of infill frame structure under laterally reserved low cyclic loading is studied and the corresponding hysteresis curve is obtained.
