［摘要］某工程連橋最大跨度達(dá)62m，結(jié)構(gòu)總高度僅為2.4m，采用空間鋼桁架結(jié)構(gòu)。由于連橋豎向自振頻率與步行頻率接近，為滿足結(jié)構(gòu)安全及舒適性使用要求，采用TMD系統(tǒng)進(jìn)行減振設(shè)計。實測結(jié)果表明，TMD減振效果良好，可為類似工程參考。

Abstract: The span of a footbridge of a building is larger than 62 meters, the structural height of the footbridge is only 2.4 meters, spatial steel truss is used. As the natural vertical frequency is very close to the walking frequency. The TMD is used to decrease the walking-caused vibration for structural safety and walking comfortable. The measured results show that the effect of TMD is great. This article can be refer for similar design.
Keywords: large span footbridge; comfortable degree；TMD
