摘要

TMD对简谐激励和风荷载引起振动的控制效果得到了一致的肯定,然而关于TMD地震控制的效果还没有一致的结论。文中比较了几种有代表性的TMD参数优化方法所确定的TMD参数;利用MAT-LAB编制了计算程序,分析了不同方法所确定的TMD参数用于地震控制时,控制效果的差别;从反应谱的概念出发,研究TMD对单自由度结构的地震控制效果。结果表明,TMD总体上对于单自由度结构的地震响应是有控制效果的,结构本身响应越大,控制效果越好;结构本身响应很小的时候,TMD有放大结构响应的现象,但由于结构本身响应很小,放大后的结构响应也不会导致结构有破坏的危险。
The control effectiveness of TMD to vibration caused by harmonic excitation and wind is affirmed by all the researchers,while there is not coincident conclusion about the control effectiveness of TMD to mitigate structural seismic response.In this paper,the different methods for TMD parameter optimization are compared and their seismic control effectiveness is compared.Based on the concept of response spectra,the control effectiveness of TMD for a SDOF system seismic response is studied.The results demonstrate that TMD is effective to mitigate seismic response of the SDOF in general.
