摘要
本文分析了不对称高层建筑平移 扭转耦联振动的动力特性及其地震作用下的动力反应 ;根据结构控制的基本理论提出了用LTTMD控制系统 ,控制不对称高层建筑多阶振型的计算方法 ,编制了相应的计算机程序 ;
In this paper,the coupled lateral?torsional vibration characteristics and dynamic response of asymmetrical tall buildings under seismic effect are analyzed Based on the basic theory of structural control,the principle and method of computation using the LTTMD system to control the high order vibration modes of asymmetrical tall buildings are presented The corresponding computer program is compuiled Various parameters,which affect the earthquake mitigation effect of the LTTMD control system,are studied in detail
