摘要
针对单段核筒悬挂建筑结构体系,推导出地面简谐激励作用下绝对加速度和相对位移响应的频率传递函数;讨论了物理参数对响应的影响。将理论结果与振动台试验结果作比较。
For the core tube suspension building structure in one hanger suspended,this paper derives at first the frequency responses of absolute acceleration and relative displacement under the action of ground harmonic excitation,then discusses the effect of parameters of frequency,damping and mass ratio on the responses of structure.Compared with the results of vibrating table test,the coincidence is very good.The results obtained in the paper are useful to the random dynamic analysis for the suspension building structures.
