- Abstract:
- Based on characteristics of the variable cross-section box girder with corrugated steel webs,considering girderheight and bottom plate from the force equilibrium of thickness,the elastic element,the web’ s shear stress formula was derived.It was shown got that shear stress of variable cross-section composite box girder with corrugated steel webs was sheared by top and bottom concrete plate and corrugated steel webs.It was concluded that the variable cross-section composite box girder’ s shear was caused by the section’s shear force,in addition,also including additional shear stress which was produced by bending moment and axial force.Through comparing of the formula solutions section and variable’ s formula and FEA results of constant section,it is indicated that the shear stress calculation formula has higher calculation precision.Finally,based on testing the formula,taking into account three load cases,variable cross-section box girder with corrugated steel webs shear force transfer efficiency was given.
