摘要
将主结构作为多自由度推导了受控振型的频率幅值响应方程 ,在此基础上比较了具有STMD和MTMD结构受控振型不同的频率响应特征并分析TMD布设位置对制振效果的影响 ,最后根据推导的频率幅值方程针对一座特大桥进行了MTMD参数分析和设计 ,并给出了在
In this paper, frequency amplitude distribution response equation of controlled mode of vibration is deduced by considering the main structure as multi degree of freedom. on the basis, frequency response characteristics of different controlled modes of vibration with STMD and MTMD structure respectively are compared, and the effect of TMD arrangement upon vibration control is also discussed. In the end, MTMD parameter analysis and design are carried out in connection with an extra long bridge, and the results of time history analysis under the influence of two seismic waves are given.
