双调制非平稳地震波作用下巨子型有控结构动力响应分析
|
摘要
巨子型有控结构体系是超高层建筑结构体系中一个新的分支。文章将地震地面运动作为随机过程,结合双调制函数生成人工地震波,对巨子型有控结构进行双调制非平稳地震波作用下的响应分析,并与普通巨型框架结构在相同地震波输入情况下的动力响应进行了对比。结果表明,巨子型有控结构在双调制非平稳地震作用下的层间位移角均满足抗震规范中层间位移角限值的要求,并且其位移与加速度响应小于同等工况下巨型框架结构的动力响应。
Aim.To our knowledge,there is no paper in the open literature dealing with the model application to calculating the seismic response of the mega-sub controlled structural system(MSCSS) mentioned in the title.Sections 1 and 2 of the full paper explain our application;the model used is taken from Ref.6.Their core consists of:(1) we treat the earthquake motion exerted on a super-tall building structural system as a stochastic process and generate the artificial seismic wave with the double modulation function;(2) we investigate the seismic response of the MSCSS under double modulation and non-stationary earthquake excitation and compare it with that of the conventional mega-frame structure under the same excitation.The simulation and calculation results,given in Figs.4 through 7,demonstrate preliminarily that:(1) the interlayer displacement angle of the MSCSS under double modulation and non-stationary earthquake excitation can meet the requirements of the interlayer displacement angle threshold value mentioned in China's seismic resistance code;(2) the displacement response and acceleration response of the MSCSS are smaller than those of the conventional mega-frame structure under the same excitation.
