Analysis on Truss Beam Structure of a Long-span Aluminium-alloy Footbridge
As a high-class new bridge structural material,the aluminium alloy has the characteristics of light and high strength,each maintenance,low-carbon environmental protection,convenient and fast construction and high landscape performance.In recent years,the aluminium alloy structure has been more applied in the urban footbridges.But there is rare application case of long-span aluminium alloy footbridge.Taking Foshan Avenue Footbridge(intersection of Lanshi Road)in Chancheng District of Foshan as an example,the superstructure design of the long-span aluminium alloy footbridge is introduced in detail.The superstructure of the long-span aluminium alloy footbridge is selected and analyzed through MIDAS and 3D3S finite element models,which can be referred for the superstructure design of the long-span aluminium alloy footbridge.
