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 paper presents a finite element analysis and static-load experimental verification on stress performance of corroded prestressed concrete bridge at Bai-Kong bridge of Shijiazhuang City on Beijing-Guangzhou Railway. At first, calculation of the actual bridge is simplified, mesh of the finite element of the bridge model is introduced, including the mesh of the finite element of undamaged bridge and the corroded bridge. For the situation above-mentioned, the finite element calculation result of the actual bridge is also presented in this paper. The graphic of the static load on the actual bridge and the testing spots distribution are described in this paper. Finally, the contrast between the static test result and the finite element calculation result is presented in this paper too.

Simplified Modeling

Geometry modeling and meshing are directly related to the effectiveness and accuracy of the finite element calculation. In order to improve above two key technologies, small size ferromagnetic objects on the ship deck are simplified, and the parametric idea is introduced into the ship model meshing. A typical ship model is set up on the platform of software FLUX. The above improved technologies are tested in FLUX in the earth magnetic environment. The experimental results show that the simplified modeling can greatly reduce the amount of calculation, and parametric meshing can effectively improve the computational efficiency, which proves that the above improved method is an efficient method for the finite element calculation of the ship magnetic field.
