Pseudo-dynamic test and dynamic response analysis on structure with multi-dimensional earthquake isolation and mitigation device
本文介绍了加入多维隔减震装置的大跨网架结构拟动力试验，通过对比加与未加多维隔减震装置的大跨网架结构的动力响应，发现多维隔减震装置对于大跨网架结构具有良好的减震效果。同时，建立该大跨网架结构模型的有限元模型，进行动力反应数值分析，通过对比试验中结构的响应与数值分析的结果，说明了该有限元模型能够很好地模拟无支座情况下的试验结果。利用粘弹性材料标准线性固体模型，根据现有的装置性能试验结果确定相关参数，得到多维隔减震装置的有限元模型，并将其加入前述大跨网架结构有限元模型中进行动力反应分析。结果表明，该有限元模型能够很好地模拟加入支座后的大跨网架结构。
In this paper, the pseudo-dynamic test on a long-span grid structure with and without the multi-dimensional earthquake isolation and mitigation device (MEIMD) is present. The comparison of dynamic responses of the grid structure with and without MEIMD shows that MEIMD has great earthquake isolation and mitigation ability. Besides, the finite element model of the grid structure without MEIMD is established and the numerical dynamic reaction is carried out. And the results show that the finite model can simulate the actual structure well. Using standard linear solid model and based on the property test results, the parameter of the finite element of MEIMD is determined. And the numerical simulation of the grid structure with MEIMD is carried out. The results show that the finite element can simulate the grid structure with MEIMD.
