JiaoJiang second bridge is a 5-span continuous cable-stayed bridge with double pylons and double cable planes whose main span is 480m. The main girder’s cross section has used a new type of composite beams --Semi-enclosed steel box composite girder, this article describes the design concept ofto this new type of composite girder, researched and analyzed the overall mechanical behavior of the composite girder, the spatial bearing behavior of the composite girder’s connecting piece, the segmental assembling technology of the composite girder and the mechanical behavior of its connecting piece by means of experiment and finite element calculation, then looks forward to the popularization and application prospect of this new type of composite girder.

Stress Experiment

We designed the experimental model of main tower of Tianjin Haihe bridge according to photoelastic experiment theory and proceeded stress experiment at the positions where the stress calculation is precise. Then we compared the experimental results with the finite element calculation results to verify whether the photoelastic experiment fits the stress calculation of main tower of cable-stayed bridge. The experimental results show that the photoelastic experiment could supply gist for the stress calculation of main tower of cable-stayed bridge, which is significant far and wide.

Warping Stress

Taken the Chongqing PC composite box girder with corrugated steel web for background , spatial finite element calculation model is set up by adopting the mixed unit, the influence about geometric parameters of corrugated steel perforation is analyzed by used linear and nonlinear finite element calculation of steel box girder .It shows that bending stress and warping stress was reduced by increasing the bending angle of corrugated steel webs of composite beams, while the buckling strength improved obviously; the ratio of the top slab and the floor slab maximum thickness of box girder to the corrugated steel perforation should be about 20; the mechanical properties of composite beams will be improved by reducing the length of straight slabs of corrugated steel webs.

The tapered cross-section beams made of steel-concrete composite material are widely used in engineering constructions and their dynamic behavior is strongly influenced by the type of shear connection jointing the two different materials. The 1D high order finite element model for tapered cross-section steel-concrete composite material beam with interlayer slip was established in this paper. The Numerical results for vibration nature frequencies of the composite beams with two typical boundary conditions were compared with ANSYS using 2D plane stress element. The 1D element is more efficient and economical for the common tapered cross-section steel-concrete composite material beams in engineering.
