［摘要］通过对3片不同形式剪力墙进行低周反复荷载试验，研究了普通配筋剪力墙、交叉斜向配筋空心剪力墙及交叉斜向配筋实体剪力墙在相同受力条件下破坏形态、承载能力和抗震性能。研究表明：3种墙体均呈现压弯破坏形态，受拉钢筋先屈服，然后混凝土压碎；与普通配筋剪力墙相比，交叉斜向配筋空心剪力墙能够减轻自重，且洞口不会削弱墙体的受力性能，试件表现出良好的延性和耗能性能；与交叉斜向配筋实体剪力墙相比，交叉斜向配筋空心剪力墙的刚度、延性、耗能性能略有下降，但下降幅度不大。提出了交叉斜向配筋实体剪力墙和交叉斜向配筋空心剪力墙的受弯承载力计算公式，计算结果与试验比较吻合。该研究为后继装配式建筑提供了一种新型墙体模型。

Abstract:Three shear walls of different forms were tested under cyclic loading to study the failure modes，bearing capacity and seismic performance among traditional shear wall，cross diagonal reinforcement hollow shear wall and cross diagonal reinforcement solid shear wall. The study shows that the three walls present bending failure modes: tension reinforcements yield first and then the concrete cursh. Compared with trational shear wall，cross diagonal reinforcement hollow shear wall can  reduce the weight， and the hollow holes will not weaken the mechanical performance of the wall. Specimen shows good ductility and energy dissipation performance. Compared with the cross diagonal reinforcement solid shear wall， the stiffness，ductility and energy dissipation performance of cross diagonal reinforcement hollow shear wall are decreased, but the decrease is not significant. The bending bearing capacity calculation formula of cross diagonal reinforcement solid shear wall and cross diagonal reinforcement hollow shear wall were put forword and the calculated results are quite consistent with the experimental results. The results provide a new type of wall model for the subsequent assembly building.

Keywords:hollow shear wall; cyclic loading test; seismic performance; mechanical performance
