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。
In order to study the mechanical properties, failure characteristics and seismic performance of L-shaped shear wall with prefabricated core-shell insulation under low cyclic loading, , One for the cast-in-place comparative specimen) was used to conduct quasi-static tests to study the failure morphology, load bearing capacity, hysteresis curve, skeleton curve, stiffness degradation and energy dissipation capacity of each specimen. The experimental results show that the axial compression ratio has obvious influence on the seismic performance of L-shaped shear wall with prefabricated sandwich core. The L-shaped shear wall with prefabricated core-shell insulation has good seismic performance, which can replace the in-situ sandwich shear wall for In actual project.
