高层钢结构-MTLD系统抗震优化设计方法
|
摘要
为方便工程设计 ,基于导出的结构 -MTLD系统动力放大系数控制指标 ,利用数值分析技术 ,给出了MTLD系统最优设计参数、MTLD系统优化设计步骤和结构 -MTLD系统抗震设计方法。利用时程分析方法 ,给出了钢结构TLD和MTLD地震反应控制设计算例以说明其具体应用。
For the convenience of the engineering design,on the basis of the controllability index(i.e.D max )and using numerical analysis technique,the optimum parameters of MTLD were given.The optimum design steps for MTLD and the whole design procedure for structure MTLD system subjected to earthquake were also introduced.A design example for steel structure MTLD/TLD systems under seismic excitation was given to illustrate the application of the method proposed in this paper with the help of the time history analysis.
