本文在框支密肋复合墙结构振动台试验的基础上，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振型、自振频率、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，建立的有限元模型能较好的反应框支密肋复合墙结构的基本动力特性，采用有限元模型不仅可以提高建筑结构抗震分析的效率，弥补了振动台试验的不足，也更有助于分析其抗震性能和耗能机制，从而证明了数值模拟的合理性和可靠性，进而得出了结构的动力特性与弹塑性地震响应的基本规律，为今后该结构的工程实践和科学研究提供了基础。
Abstract
In this paper, the frame supported multi ribbed composite wall structure vibration table test basis, using finite element software ABAQUS, establish the nonlinear finite element model of the structure, and the earthquake response of the structure under several typical working condition test of numerical simulation calculation, selection of vibration type, representative of the natural frequency of vibration, acceleration, inter story displacement angle, structure failure modes analysis results, the results are compared with experimental results. The analysis results show that the numerical simulation and shaking table model test agree well with the established finite element model can reflect the frame supported multi ribbed composite wall structure of the basic dynamic characteristics, using the finite element model can not only improve the efficiency of seismic analysis of building structure, to make up for the lack of shaking table test, is also more conducive to analysis the seismic performance and energy dissipation mechanism, so as to prove the rationality and reliability of the numerical simulation, and conclude that the dynamic properties of the structure and the basic rules of the elasto plastic seismic response, and provides a basis for the future of the structure of the engineering practice and scientific research.
