基于1/6比例框支密肋复合墙结构模型的振动台试验,采用ABAQUS有限元软件,建立该结构的非线性有限元模型,并对该结构在试验的几种典型工况下的地震反应进行数值模拟计算,选取了具有代表性的加速度、层间位移角、结构破坏形态等分析结果,与试验结果进行对比。分析结果表明:数值模拟与振动台模型试验吻合较好,证明了模型试验的可靠性和数值模拟的合理性,进而得出了本结构的动力特性与地震响应基本规律,为今后该结构的工程实践和科学研究提供了基础。

The shaking table test of a frame-supported multi-ribbed composite wall structure model with proportion of 1/6 was conducted. Using ABAQUS finite element software, the nonlinear finite element model of the structure was established. The seismic responses of the structure under several typical test working conditions were simulated numerically. Its acceleration, inter-story displacement angle, and structure failure status were chosen and analyzed, the results were compared with the test ones. The analysis results showed that the results of numerical simulation agree well with those of the shaking table model test; the reliability of the shaking table model test and the rationality of the numerical simulation were verified; and then the dynamic characteristics and the basic rules of seismic responses of the structure were obtained. The study results provided a basis for the further engineering practice and scientific study of the structure.
