摘要
为改善复杂高层建筑中剪力墙的抗震性能,进行剪跨比为1的2个无内置钢板的型钢混凝土剪力墙试件和12个有内置钢板-混凝土组合剪力墙试件的低周反复加载试验,揭示轴压比和内置钢板厚度(即墙身含钢率)对试件抗震性能的影响规律。结果表明,相对于无内置钢板的型钢混凝土剪力墙试件而言,内置钢板-混凝土组合剪力墙试件的承载能力、变形能力和耗能能力均显著提高,但是要使这三者综合最佳,应该将墙身含钢率控制在一定范围内,且设计轴压比应控制在0.50以内。
In order to improve the seismic performance of the shear walls in complex high-rise buildings, a series of low cyclic loading tests were carried out on 14 specimens, including 2 composite shear walls without embedded steel plate reinforcement and 12 composite shear walls with embedded steel plate reinforcement. The shear-span-ratio of the 14 specimens were all 1.0. The aim of the tests is to study the influence of axial compression ratio and the thickness of the embedded steel plate （steel ratio of shear wall） on the seismic performance of the specimens. The results indicate that compared to those of the composite shear walls without embedded steel plate reinforcement, the load-carrying capacity, deformation capacity and energy dissipation capacity of the composite shear walls with embedded steel plate reinforcement are significantly improved. However, to achieve the optimal comprehensive effect of the three factors, the steel ratio of the shear wall should be controlled in a certain range and the design axial compression ratio should be within 0.5.
