底层大空间高位转换高层建筑振动台试验研究

Earthquake simulation shaking table test of a high-rise structure with large space on ground floor and high transfer slabs

通过对一座底层大空间、采用高位厚板转换层的框支剪力墙高层建筑的模拟地震振动台试验,分析研究了该结构的抗震性能.按1∶30缩比设计制作了底层大空间高层建筑模型,测试了模型结构的动力特性及在1个场地波和2个天然波激励下的地震反应特征.试验及分析结果表明:该结构的抗震性能基本满足现行规范的要求;结构的转换层、剪力墙厚度发生变化及钢管混凝土柱转变为混凝土柱的36层附近是抗震薄弱部位,在抗震设计中应该予以加强.

Seismic behaviors of a high-rise frame-shear wall structure with large space on ground floor and high thick transfer slabs is studied on the shaking table.A 1∶30 scale model of the building is constructed,the dynamic characteristcs and earthquake responses of the model under three earthquake waves which include one synthetic wave and two natural waves are researched.The result of test and analysis of the model show that seismic behaviors of the buildings are basically satisfied with request of the code for ...
