摘要

对1/6缩尺框支密肋复合墙结构模型进行振动台试验,结构模型经历了弹性阶段、开裂直至破坏全过程,研究了结构在不同阶段的动力特性及动力反应,以El Centro 波、Taft波、人工波为输入地震波,分别按设防烈度7度多遇、基本、罕遇、超罕遇以及8度多遇、基本、罕遇、超罕遇地震作用进行试验,研究了模型结构在各阶段地震作用下的加速度、位移和应变反应,以及结构的破坏形式和破坏机理。试验结果表明:框支密肋复合墙结构其转换层的破坏模式为剪切型破坏,塑性变形主要集中在转换层;框支密肋复合墙结构各层的绝对加速度反应主要取决于前两阶阵型,高阶阵型的影响很小,其中第一阶阵型起着绝对控制作用。

Abstract

The shaking table test of a 1/6 scale multi-rib composite wall supported on frame, the test structure has undergone elastic stage, cracking up the whole process of destruction, the dynamic characteristics and the dynamic response of the structure in the various stages, inputting the El Centro wave, Taft wave, artificial seismic wave input, according to the seismic fortification intensity of 7 degree frequent, basic, rare, very rare and 8 degree frequent, basic, rare, very rare earthquake test,to study the model structure in each phase under the action of earthquake acceleration, displacement and strain responses, as well as the structure of the failure mode and failure mechanism. The results showed that: frame supported ribbed composite wall structure of its conversion layer shear failure mode of destruction, plastic deformation is mainly concentrated in the conversion layer; frame supported ribbed composite wall structure layers absolute acceleration response depends primarily on the first two bands formation, formation of a small order, wherein the first phase formation plays a role in absolute control.
