摘要
以常州现代传媒中心工程项目为例,采用ETABS软件对结构进行分析,通过改变主体结构高度和塔楼高度,比较在不同刚度比、周期比条件下的楼顶塔在地震作用下的"鞭梢效应",得出类似工程楼顶塔地震力放大系数发展规律。
Taking the modern media center project in Changzhou as an example, this paper analyzed the structure using ETABS software, by changing the main structure height and tower height, compared the“whiplash effect” of roof tower under earthquake force with different stiffness ratio, cycle ratio conditions, gained the development law of similar engineering roof tower earthquake force amplification coefficient.
