摘　　要：针对大跨径Y墩钢结构人行天桥的设计开展研究,Y墩与上部结构刚接,可有效降低桥梁高度并提升其美学价值,同时,通过有限元计算分析,详细评估人行天桥的动力特性、结构强度、结构刚度、整体稳定性等关键指标。研究结果表明:人行天桥的动力和静力性能均满足规范要求,结构设计方案合理、可行。研究中强调桥梁设计应充分考虑环境因素和边界条件,以实现桥梁工程的人性化设计和可持续发展,研究成果可为同类人行天桥设计提供参考。The research examines the design of a long-span Y-pier steel pedestrian bridge.The rigid connection between the Y-pier and the upper structure reduces the bridges beam height,enhancing its aesthetic appeal.Through finite element analysis,critical metrics like dynamic characteristics,structural strength,stiffness and stability are evaluated.The findings show that both the dynamic and static performances meet regulatory requirements,indicating the designs rationality and feasibility.The research also underscores the importance of considering environmental factors and design boundary conditions to achieve humanized design and sustainable development of bridge engineering.The research results can provide reference for the design of similar pedestrian bridges.
