摘要：为研究钢筋短搭接后浇超高性能水泥基复合材料(UHPC)连接的预制装配式混凝土剪力墙的抗震性能，对4榀剪跨比为2.27的混凝土剪力墙试件进行了拟静力试验。为了探讨轴压比对其抗震性能的影响规律，其中1榀为设计轴压比为0.2的现浇剪力墙，3榀为设计轴压比分别为0.2、0.33、0.47的预制装配式剪力墙。试验结果表明：所有试件均以剪压破坏为主，各试件刚度退化与强度退化规律基本相同，位移角均远大于规范中规定的弹塑性层间位移角限值1/120。与现浇试件相比，轴压比同为0.2的预制装配式试件的抗裂能力、承载力和刚度均有所提高，延性与耗能能力略低；随着轴压比增大，预制装配式试件抗裂能力、承载力和刚度显著提高，滞回曲线出现明显的捏拢现象，延性和耗能能力有所降低。

Experimental research on seismic performance of precast concrete shear wall connected with ultra high performance cementitious composites
Abstract: Quasi-static tests of four concrete shear wall specimens with shear span ratio of 2.27 were conducted aimed at studying on seismic performance of precast concrete shear wall connected with ultra high performance cementitious composites( UHPC) by short lap of reinforcement. In order to investigate the influence law of axial compression ratio on the seismic performance, one full cast-in-place wall with design axial compression ratio of 0.2 was considered, and three precast specimens with design axial compression ratios of 0.2,0.33 and 0.47 were considered. The experimental results show that all the specimens are mainly shear compression failure, the law of the stiffness degradation and strength degradation of each specimen are basically the same, and displacement angles are much larger than the limit 1/120 of elastic-plastic interlayer displacement angles specified in the code. Comparing with the cast-in-place specimen, when the axial compression ratio is 0.2, the crack resistance, bearing capacity and stiffness of precast specimens are improved, and the ductility and energy dissipation capacity are slightly lower. With the increase of axial compression ratio, the crack resistance, bearing capacity and stiffness of precast specimens are significantly improved, and the hysteresis curve is obviously pinched, and the ductility and energy dissipation capacity are reduced.
