［摘要］提出了一種新型的裝配整體式剪力墻結(jié)構(gòu)形式，其預(yù)制構(gòu)件為帶混凝土貫通肋的空心墻構(gòu)件，現(xiàn)場在空腔內(nèi)搭接豎向鋼筋、澆筑混凝土形成疊合剪力墻構(gòu)件。為研究新型預(yù)制剪力墻的抗震性能，以某實(shí)際工程為背景，完成6個(gè)足尺剪力墻試件的擬靜力試驗(yàn)，主要模擬不同剪跨比及不同形式的墻體。試驗(yàn)結(jié)果表明，提出的新型預(yù)制剪力墻試件的承載力、剛度、破壞模式、耗能能力等性能與現(xiàn)澆試件一致，可按與現(xiàn)澆結(jié)構(gòu)相同的方法進(jìn)行此類裝配整體式剪力墻構(gòu)件的設(shè)計(jì)。

Abstract:A new type of pre-cast monolithic shear wall structural system was proposed, the pre-cast component is hollow wall component with concrete longitudinal ribs，and vertical steel bars are overlapped in the cavity and concrete is poured on site to form a composite shear wall component. In order to study the seismic performance of the new pre-cast shear wall, based on an actual project, a pseudo-static test of 6 full-scale shear wall specimens was completed, mainly to simulate different shear span ratios and different forms of walls. The test results show that the bearing capacity, stiffness, failure mode, energy dissipation capacity of the new type of pre-cast shear wall specimens are in accord with the cast-in-place specimens. The new type of pre-cast shear wall can be designed in the same way as the cast-in-place structure.
Keywords:pre-cast monolithic shear wall;shear wall superposed with longitudinal rib;reinforcement lapping;pseudo-static test;seismic performance
