Study on Web Parameters of Prestressed Concrete Composite Box Girder with Corrugated Steel Web

Abstract:

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.
