对4个装配式空心剪力墙试件进行拟静力试验,模拟了不同的轴压比和剪跨比对试件抗震性能的影响。通过低周往复加载试验得到试件的滞回曲线,并分析其延性、耗能性能和刚度特征。试验结果表明:装配式空心剪力墙的抗震性能和普通钢筋混凝土剪力墙抗震性能相似,且空心孔洞和水平拼接缝不会削弱墙体的受力性能,各个试件均表现出良好的延性和耗能能力,因此可以通过提高水平拼接缝的位置改善墙体抗震性能。
Quasi-static tests on four assembled hollow shear wall specimens were carried out to simulate the influence of different axial compression ratio and shear-span ratio on the seismic performance of specimens. The hysteresis curve of the specimen was obtained by low-cycle reciprocating loading test, and its ductility, energy dissipation and stiffness characteristics were analyzed. The experimental results show that the seismic performance of fabricated hollow shear walls is similar to that of common RC shear walls, and the hollow holes and horizontal splices do not weaken the performance of the wall. All specimens show good Ductility and energy dissipation capacity, it can improve the seismic performance of the wall by increasing the level of horizontal joints.
