竖向钢筋搭接的装配整体式剪力墙抗震性能试验研究

摘要

提出了一种新型的装配整体式剪力墙结构形式,预制剪力墙内的竖向钢筋采用搭接连接.为研究这种新型预制剪力墙的抗震性能,以某实际工程为背景,完成了8个足尺剪力墙试件的拟静力试验,主要模拟不同剪跨比下的内墙和外墙.试验结果表明,本文提出的新型预制剪力墙,其承载力、刚度、破坏模式、耗能能力等性能与现浇试件一致,可以按照与现浇结构相同的方法进行设计.%A new type of pre-cast shear wall that the vertical reinforcements are lapped in the cast-in-situ region at bottom joint of the PC wall is proposed. In order to study the seismic performance of the PC wall and the joint, eight full scale reinforced concrete shear wall specimens simulating interior and exterior walls with different shear span ratios are tested. The test results show that the bearing capacity, stiffness, failure mode, energy dissipation capacity of pre-cast specimens are in accord with the cast-in-place specimens. The new type of pre-cast shear wall can be designed by similar method with cast-in-place shear wall.
