• Shear lag
• Spatial cable
• Static properties
• Total bridge model test

The Jiangdong Bridge in Hangzhou is a spatial cable self-anchored suspension bridge, width 47m, single-column pylon, separate steel box and single-span suspension. A total bridge model is designed with a geometric scale of 1:16 and a force scale of 1:4, and the structural static property in service stage is studied using model test. Influence lines of internal force and displacement, and the corresponding loading interval for maximum moment are determined. Structural behavior in different situations is thoroughly studied. Test and theoretical analysis show that structural mechanical property is linear for the completed bridge. There exists shear lag effect in the thin-wall wide box girder, which obviously impacts the stress and deformation of the box girder, but the influence on internal forces of the main cables and hangers is quite small.
