The purpose of this study is to investigate the strength and failure of various shapes of plate girders with corrugated and flat webs under patch and distributed loading First, the failure mechanisms of plate girders were studied then by using the studies, verify the validity of the samples a comparison between the numerical model and the laboratory sample has been made. a plate girder with a flat web is considered as the base web as well as plate girders including square, triangular, trapezoidal, flat with stiffener, combined web and sinusoidal shapes. The amount of steel used for the analysis and comparison of the samples is assumed to be the same, Modeling of the samples was done by ABAQUS software, finally comparing the strength of this type of plate girders with a flat girder, among them, the best form of corrugated girder in terms of strength under patch and distributed loads was presented. The results obtained showed that corrugation of the plate girders changes their behavior and better performance under patch and distributed loading. Also, the geometrical parameters of the model such as: wave angle, web thickness, have had a great impact on the strength of numerical models, so that in some web shapes, including triangular webs, under a distributed load, Reducing the thickness of the web significantly reduces the resistance of the sample, and in the composite web under distributed loading, the change in the fold angle and the web thickness did not have much effect on the model's resistance.
