型钢自密实混凝土叠合剪力墙抗震性能试验

Experimental study on seismic performance of profile steel concrete composite shear wall

试验设计了3片型钢混凝土叠合剪力墙与1片型钢普通混凝土剪力墙,通过低周反复试验,研究分析型钢自密实混凝土叠合剪力墙的抗震性能,分析其破坏形态、滞回特性、延性以及耗能能力与型钢混凝土剪力墙的差异。结果表明:型钢混凝土叠合剪力墙破坏形态、滞回特性与型钢混凝土剪力墙基本相同,延性以及耗能能力略低于型钢混凝土剪力墙;型钢自密实混凝土叠合剪力墙与型钢混凝土叠合剪力墙试验结果相近,延性、耗能能力等抗震性能无明显差别。

Three profile steel concrete （PSC） composite shear walls were designed. The seismic performance, failure patterns, hysteretic characteristics, tensility, and energy-dissipating capacity were studied under the cyclic loading. Experimental results showed that the failure patterns and hysteretic characteristics of profile steel self-compacting concrete （SCC） composite shear walls were nearly same to PSC shear wall, besides having lower capacity of ductility and energy-dissipating. Moreover, there was no significant difference in ductility and energy-dissipating capacity between profile steel SCC compiste shear wall and PSC composite shear wall.
