Research of Three-Truss Cable-Stayed Bridge Spatial Characteristic
Wuhan Tianxingzhou Yangtze River Rail-cum-Road Bridge is the first four line rail cable-stayed bridge in china, with three-truss cross section. The new structure presents complex load performance, especially the spatial mechanical characteristics, because the bridge supports six lanes and four railway load, inevitably the main truss will produce a great torque, leading to three-truss cross section distortion and warping deformation. Analysis of the whole bridge spatial structures is carried out. The space shear flexible beam grillage model is used for bridge structure simulation, the upper and lower vertical member and the horizontal link simulated with beam element, while the pylon with space beam element, the cable with cable element. Though the calculation of the cable force and stress, the main girders stress, the pylon stress, the displacement of the main girder and the pylon, it can be shown that the space force and displacement keep within the standard requirement.
