［摘要］预制混凝土空心模剪力墙是一种以开设双向孔洞的预制混凝土板为基本装配单元，通过在孔洞内穿插钢筋后浇筑混凝土形成整体的结构体系。为提高施工效率，提升剪力墙的受力性能，对原空心模相关构造进行了改进，设计了两个空心模剪力墙试件； 通过恒定轴力作用下的拟静力试验，研究了空心模改进后剪力墙的破坏形态和受力性能，对比分析了空心模构造对剪力墙受力性能的影响。试验结果表明：空心模构造对剪力墙试件的自适应分缝特性、延性以及水平承载力影响较小； 但空心模内竖向后浇混凝土圆柱的连续性对墙体竖向荷载的传递性能影响较大，可以改变空心模宏观竖向裂缝的出现位置以及形成状态。

Abstract:Precast concrete hollow mold shear wall is a kind of precast concrete slab with two-way holes as the basic assembly unit, which forms an integral structural system by inserting steel bars in the holes and then pouring concrete. In order to improve the construction efficiency and the mechanical performance of the shear wall, the related structure of the original hollow mold was improved, and two hollow mold shear wall specimens were designed; through the pseudo-static test under constant axial force, the failure form and mechanical performance of the shear wall after the improvement of the hollow mold were studied, and the influence of the structure of the hollow mold on the mechanical performance of the shear wall was comparatively analyzed. The test results show that the structure of the hollow mold has little effect on the adaptive splitting characteristics, ductility and horizontal bearing capacity of the shear wall specimen; however, the continuity of the vertical post-cast concrete column in the hollow mold has a greater influence on the vertical load transfer performance of the wall, and can change the position and formation of macroscopic vertical cracks in the hollow mold.

Keywords:hollow mold; precast shear wall; hollow mold shear wall; vertical crack; mechanical performance
