［摘要］上海天文館局部存在40m長大懸挑區(qū)域，易產(chǎn)生人致振動問題。通過對結(jié)構(gòu)在步行激勵荷載作用下的計算，采用TMD阻尼器對大懸挑區(qū)域進行振動控制，有效地降低了人致振動加速度峰值，減振效率約為59%。對存在大懸挑結(jié)構(gòu)形式的空間結(jié)構(gòu)的人致振動問題研究具有一定參考意義。

Abstract:In Shanghai Planetarium, there is a 40m-long cantilever area which easily causes human-induced vibration problem. By the analysis and calculation for the structure under the influence of pedestrian excitation, tuned mass dampers (TMDs) were used in the area to reduce the vibration. The peak of the human-induced vibration acceleration was effectively reduced by about 59%. The result could be a reference for the study on human-induced vibration control of spatial structures with long cantilever area.
