预制钢筋混凝土框架内嵌竖缝剪力墙（ CFPCW）体系融合了框架和剪力墙2种结构的特点，又具有较好的延性，是一种新型抗震结构体系。将有限元分析方法与试验研究成果相结合，研究CFPCW体系在水平荷载作用下的力学性能。结果表明：竖缝剪力墙在加载中，首先在竖缝附近产生应力集中并引起混凝土损伤，之后破坏范围逐渐扩展至缝间墙，框架结构损伤程度相对较轻。从竖缝剪力墙的应力和损伤云图可以看出，竖缝剪力墙的变形主要是以弯曲变形为主，缝间墙的变形类似于壁柱。 CFPCW结构中竖缝剪力墙刚度下降平缓，整体结构具有较高的水平承载力和延性。

The prefabricated reinforced concrete frame with infill slit shear walls ( CFPCW ) combines advantages of a frame and a shear wall, and possesses relatively good ductility, it is considered as a new type of aseismic structure. A method that combined the finite element method with the experiment results was used to study the mechanical property of CFPCW under horizontal forces. It was found that the stress concentration occurred around the silts in the loading process, which caused the concrete structure damage. With the increase of horizontal loading, the damage range increasingly extended into walls, but the damage of reinforced concrete frame was lighter. From the stress and damage figure of silts-wall, the deformation of shear walls was mainly bending deformation, which were similar to wall-columns. In the loading process, the lateral stiffness of slits wall decreased slowly so that it could get higher horizontal bearing load and better ductility.
