巨-子型有控结构体系在地震激励下的响应控制特性
|
摘要
为研究巨-子型有控结构体系MSCSS(Mega-Sub Controlled Structural System)在地震作用下的响应特性,建立了MSCSS在随机地震激励下的动力方程,推导了结构响应计算表达式,对MSCSS在随机平稳及非平稳地震激励下的响应控制特性分别进行了对比计算研究,讨论了相对结构参数,如主子结构质量比、相对刚度比对MSCSS位移及加速度响应控制效果的影响.研究结果表明,与传统普通巨型框架结构体系相比,MSCSS在控制位移、加速度响应方面具有显著效果.
In order to investigate seismic response characteristics of the mega-sub controlled structural system(MSCSS),the dynamic equations of the MSCSS under the random seismic excitation were presented,the corresponding calculation expressions of the structural responses were derived,and the response controlling effectiveness of the MSCSS both under the stationary seismic excitations and under non-stationary seismic excitations were investigated contrastively,the influences of relative structural parameters,such as the relative mass ratio and relative stiffness ratio of the mega-frame to sub-structure,on the displacement and acceleration response controlling effectiveness of the MSCSS were discussed.The results indicate that compared with the conventional mega-frame structural systems,the proposed MSCSS presents an obvious effectiveness for controlling displacement and acceleration responses.
