摘要：通过对预制混凝土短肢剪力墙试件和现浇混凝土短肢剪力墙试件进行拟静力试验，对比二者的破坏形态、滞回性能、刚度退化和耗能性能等抗震指标。试验结果表明：预制试件与现浇试件破坏形态都为压弯破坏，角部混凝土压碎，钢筋屈曲,预制试件滞回环饱满，刚度退化平缓，有较大的位移延性系数，展现了良好的延性，各项指标与现浇试件相当，抗震性能良好。

Abstract：Thepseudo-static experiments on precast reinforced concrete short shear wall andcast-in-place reinforced concrete short shear wall were carried out . Comparedwith the cast-in-place reinforced concrete short shear wall, the failure modes,hysteresis behavior, stiffness degradation and energy dissipation performanceof the precast reinforced concrete short shear wall were obtained. Experimentalresults show that the precast specimen is similar to the cast-in-situ specimen,which presents bending failure pattern with crushing angle of concrete andbuckling reinforcement; the precast specimen has good performance, whoseindicators such as hysteresis loop back full, stiffness degradation, largerdisplacement ductility coefficient, and good ductility are close to those ofthe cast-in-situ specimen. The precast specimen indicates significantseismic performance.
