Abstract：Research purposes: The corrugated steel web of corrugated steel webs prestressed box girder is in pure shear stress state． The shear － resistant capacity of the corrugated steel web depends on the shear buckling strength of the section． The simulation was done for the defect of corrugated steel web with uniformly defect modal analysis method，and the defects were included in the material nonlinearity and geometric nonlinearity． On the basis of it，the study was done on the influences of corrugation configuration and the overall profile dimensions of the corrugated web on the ultimate shear bucking bearing capacity of the corrugated web and buckling mode for providing the reference to calculation of the similar bridge．
Research conclusions: Through comparing the results of theoretical formulas and model analysis，the change tendencies of the thickness of corrugated steel webs ，wave height ，the obliquity of inclined plate，the width of straight section and the height of bean were obtained．
