［摘要］装配式剪力墙结构作为建筑产业化中比较成熟的结构体系，在装配式建筑中得到了大量应用。预制外墙板的窗下墙一般和结构构件一体预制，窗下墙的刚度对预制外墙的整体刚度有一定的影响。通过数值模拟的方式对预制外墙中窗下墙的刚度影响进行分析，将有窗下墙的预制外墙和没有窗下墙的预制外墙进行对比。结果表明，窗下墙对预制外墙的开裂荷载、极限荷载、切线刚度提高较大。

Abstract: As a relatively mature structural system, precast concrete shear wall structures has been widely used in the precast building. The wall under the window is prefabricated integrally. The stiffness of the wall under the window has a certain impact on the overall stiffness of the precast wall. By numerical simulation, the effect of the stiffness of the wall under the window was analyzed. The results show that the cracking load, the ultimate load and the stiffness of the precast wall are greatly improved by the wall under the window.

Keywords: precast concrete shear wall; stiffness; wall under window
