摘要
日晖港人行桥设计为空间Y型张弦梁形式,结构新颖、复杂、刚度小。研究该桥结构体系,包含支承系统、拉索线形、主梁交汇角度及主梁交汇形式等,分析人致振动,并提出具体减振措施。经过计算及研究,桥梁关键性能均满足要求。
Rihui Port Pedestrian Bridge is designed with Y-beam string structure. The bridge structure is novel, complicated with small rigidity. This paper researches the structural system, including bearing system, shapes of stayed cables, intersection angles of beams, intersection styles of beams and so on, pedestrian-induced vibration is analyzed and detailed damping measures are proposed. After calculations and researches, all key performances of bridge can meet the requirements.
