Abstract	A 3D finite element model of a prestressed concrete composite box girder with waveform steel webs is established by means of the composite element method. The influence about geometric parameters of waveform steel webs 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 waveform steel webs of composite beams, while the buckling strength improved obviously; the ratio of the top slab maximum thickness and the floor slab maximum thickness of box girder to the waveform steel webs thickness should be about 20; the mechanical properties of composite beams will be improved by reducing the length of straight slabs of corrugated steel webs.
