纵肋叠合装配整体式混凝土剪力墙抗震性能试验研究
Experimental study on seismic behavior of monolithic pre-cast shear walls superposed with longitudinal ribs
【摘要】 提出了一种新型的装配整体式剪力墙结构形式,其预制构件为带混凝土贯通肋的空心墙构件,现场在空腔内搭接竖向钢筋、浇筑混凝土形成叠合剪力墙构件。为研究新型预制剪力墙的抗震性能,以某实际工程为背景,完成6个足尺剪力墙试件的拟静力试验,主要模拟不同剪跨比及不同形式的墙体。试验结果表明,提出的新型预制剪力墙试件的承载力、刚度、破坏模式、耗能能力等性能与现浇试件一致,可按与现浇结构相同的方法进行此类装配整体式剪力墙构件的设计。
【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.
