Analysis on the Design of Nielsen System Tied Arch Pedestrian Overpass
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.
