摘　　要：提出了装配式剪力墙结构“强水平缝弱竖向缝”的设计方法,设计了三种不同类型的试件(矩形、T形、L形),在不同轴压比下(0.1、0.3)进行了低周往复荷载试验,研究了试件的承载能力和延性性能等。结果表明,装配式剪力墙结构力学性能良好,试件中的阻尼器达到了屈服并耗能,提高了结构整体抗震性能,并起到了很好的连接墙肢的作用。对试件截面应变分布规律进行了讨论,建立了简化的力学计算模型,推导了装配式剪力墙结构的极限抗弯承载力计算公式。The design method of"strong horizontal joint and weak vertical joint"for fabricated shear wall structure was proposed.Three types of specimens(rectangle shape,T shape,L shape)were designed.Low cyclic loading tests were carried out under different coaxial pressure ratios(0.1,0.3),and the bearing capacity and ductility property of the specimens were studied.The results show that the fabricated shear wall structure has good mechanical properties.The dampers yield and dissipate energy,which improves the seismic performance of the structure and plays a good role in connecting the wall limbs.The strain distribution law of specimen section was discussed,the simplified mechanical calculation model was established,and the calculation formula of ultimate bending capacity of fabricated shear wall structure was put forward.
