摘　　要：文章以尼尔森体系系杆拱城市人行天桥工程项目为实例,探讨了总体方案设计及主体结构设计。通过有限元软件进行主体结构受力分析,计算结果表明,结构强度、刚度、自振频率及稳定性等均满足现行规范要求。主桥采用尼尔森体系系杆拱既满足结构安全性要求,又能提供良好的景观效果,可供同类人行天桥设计项目参考。Taking the Nielsen system tied arch urban pedestrian overpass engineering project as an example,this paper discusses the overall scheme design and main structure design.The stress analysis of the main structure is carried out by finite element software.The calculation results show that the structural strength,stiffness,natural frequency and stability meet the requirements of the current specifications.The Nielsen system tied arch adopted by the main bridge not only meets the structural safety requirements,but also provides a good landscape effect,which can be used as a reference for similar pedestrian overpass design projects.
