［摘要］預(yù)制混凝土空心模剪力墻是一種以開設(shè)雙向孔洞的預(yù)制混凝土板為基本裝配單元，通過在孔洞內(nèi)穿插鋼筋后澆筑混凝土形成整體的結(jié)構(gòu)體系。為提高施工效率，提升剪力墻的受力性能，對(duì)原空心模相關(guān)構(gòu)造進(jìn)行了改進(jìn)，設(shè)計(jì)了兩個(gè)空心模剪力墻試件； 通過恒定軸力作用下的擬靜力試驗(yàn)，研究了空心模改進(jìn)后剪力墻的破壞形態(tài)和受力性能，對(duì)比分析了空心模構(gòu)造對(duì)剪力墻受力性能的影響。試驗(yàn)結(jié)果表明：空心模構(gòu)造對(duì)剪力墻試件的自適應(yīng)分縫特性、延性以及水平承載力影響較小； 但空心模內(nèi)豎向后澆混凝土圓柱的連續(xù)性對(duì)墻體豎向荷載的傳遞性能影響較大，可以改變空心模宏觀豎向裂縫的出現(xiàn)位置以及形成狀態(tài)。

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
