摘要

进行了4个钢板剪力墙模型的模拟地震振动台试验,其中2个模型为钢管混凝土边框钢板剪力墙,高宽比分别为1.7和3.2;2个模型为钢管混凝土边框内藏钢板剪力墙,高宽比分别为1.7和3.2。试验中输入Taft地震动,测试了各试件在不同峰值加速度下的时程地震反应和动力特性,分析了剪力墙的破坏特征。研究表明:钢管混凝土边框内藏钢板混凝土剪力墙与钢管混凝土边框钢板剪力墙相比,地震反应明显较小,抗震性能显著提高。
Four steel-plate shear walls were tested on the shaking table.Two of the walls are steel-plate shear walls with concrete-filled steel tube columns and the other two are composite shear walls with concrete-filled steel tube columns and embedded steel-plate.The ratio of height to width is 1.7 and 3.2 respectively.The Taft seismic ground motion was input in the shaking table test.Based on the experiment,dynamic characters,dynamic responses and failure modes of the four specimens in different seismic peak accelerations are contrastively analyzed.The results show that compared with the steel-plate shear walls with concrete-filled steel tube columns,shear walls with concrete-filled steel tube columns and embedded steel-plate have the following characteristics: the dynamic responses are significantly reduced,the seismic behavior is significantly improved.
