摘要
简述了层间隔震的工作特点及其与调谐质量阻尼器(TMD)2种控制方法的优缺点,建立了层间隔震与TMD混合控制体系的动力模型,对控制参数进行了优化分析,然后以一个21层框架剪立墙结构为例,利用ANSYS软件分析了此种混合控制的减震效果。计算结果表明层间隔震与TMD混合控制结构对于超出设防烈度的地震在层间位移上具有较明显的抗震效果。
This paper describes the working characteristic of interlayer seismic isolation. It also analyze the advantages and disadvantages of this two kinds of control methods, interlayer seismic isolation and TMD,establish a hybrid control sys- tem dynamic model of interlayer seismic isolation and TMD. And the control parameters has been optimized. Then, taking a frameshear wall structures with 21th layers as an example, analyze the damping effect of such a hybrid control by using the ANSYS software. The calculated result indicates that it has marked seismic effect, especially for the huge earthquake which is beyond the fortification intensity. The thesis aLso provides a reference ideas for researching and developing new and efficient hybrid control system.
