【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(jì)。實(shí)測結(jié)果表明,TMD減振效果良好,可為類似工程參考。
[Abstract]:The maximum span of the connecting bridge is 62 m and the total height of the bridge is only 2.4 m. The space steel truss structure is adopted. Since the vertical natural vibration frequency of the connecting bridge is close to the walking frequency, in order to meet the requirements of structural safety and comfort, TMD system is used to design the vibration absorber. The measured results show that the effect of TMD is good and can be used as a reference for similar projects.
