通过对某钢桁架桥进行人致振动计算,分别采用单人侧向人致振动计算分析和人群侧向人致振动计算分析,得出了在不同荷载工况下的位移、加速度的曲线,根据相应舒适度指标判定此桥的舒适度状况,此桥的舒适度属于比较差的范围。
通過對某鋼桁架橋進行人緻振動計算,分彆採用單人側嚮人緻振動計算分析和人群側嚮人緻振動計算分析,得齣瞭在不同荷載工況下的位移、加速度的麯線,根據相應舒適度指標判定此橋的舒適度狀況,此橋的舒適度屬于比較差的範圍。

According to the calculation of the pedestrian-induced vibration on some steel truss bridge, the paper adopts the calculation and analysis of the single-person lateral pedestrian vibration and the one of the group lateral pedestrian-induced vibration, and concludes the comfort of the bridge is still lower by judging the comfort from the displacement and curves of the acceleration in different loading construction conditions.
