[摘要]为研究预制夹芯保温L形剪力墙在低周反复荷载作用下的受力性能、破坏特点和抗震性能,对4个夹芯保温L形剪力墙试件(3个为全预制试件,1个为现浇对比试件)进行拟静力试验,研究各个试件的破坏形态、承载能力、滞回曲线、骨架曲线、刚度退化及耗能能力。试验结果表明:轴压比对预制夹芯保温L形剪力墙抗震性能的影响明显;预制夹芯保温L形剪力墙具有良好的抗震性能,可代替现浇夹芯保温剪力墙用于实际工程中。[关键词]预制夹芯保温剪力墙; L形截面; 低周反复荷载; 抗震性能中图分类号:TU375 文献标识码:A 文章编号:1002-848X(2016)10-0020-04
Low frequency cyclic loading tests of L-shaped precast sandwich insulation shear wallSong Ge1, Wang Yong2(1 School of Environment and Architecture, University of Shanghai for Science and Technology, Shanghai 200093, China; 2 Department of Art and Design, University of Shanghai for Science and Technology, Shanghai 200093, China)Abstract: To study the mechanical behavior, failure feature and seismic behavior of L-shaped precast sandwich insulation shear wall, pseudo-static tests on four L-shaped precast sandwich insulation shear wall specimens (including three wholly precast specimens and one cast-in-situ specimen for comparison) were conducted to study the failure mode, bearing capacity, hysteretic curve, skeleton curve, stiffness degradation and energy dissipation capacity of specimens. The results show that: the influence of the axial compressive ratio on the seismic behavior of the L-shaped precast sandwich insulation shear wall is obvious; L-shaped precast sandwich insulation shear wall has good seismic behavior and it can be a good substitute for in-situ sandwich insulation shear wall used in practical engineering.Keywords: precast sandwich insulation shear wall; L-shaped section; low frequency cyclic loading; seismic behavior
