摘要
文章以某大跨度人行桥为背景,通过理论分析和有限元模拟,对桥梁在行人激励下的动力响应及行人舒适性进行评价,依据评价结果提出减振方案。
In this paper,a large-span pedestrian bridge is used as the background.Through theoretical analysis and finite element simulation,the dynamic response and pedestrian comfort of the bridge under pedestrian excitation are evaluated,and a vibration reduction scheme is proposed based on the evaluation results.
