Plate girders are among the main load-bearing elements of large structures such as bridges, which, due to their type of application, must meet the necessary geometric and physical characteristics in terms of stiffness and non-buckling. Corrugated plate girders with the removal of horizontal and vertical stiffeners. Also, reducing the thickness of the web has led to a significant reduction in weight and simple implementation in building structures and bridges. The purpose of this study is to compare the strength of corrugated and flat web girders by considering the interaction effect of shear force and bending moment for different web shapes. At the beginning of this research, the behavior of corrugated girders including shear, bending and combined behavior was studied, after that, the laboratory model of Robert G. Driver et al was used to validate the numerical models. In this article, 12 samples of plate girders with simple, 7 and 8-shape, trapezoidal, triangular, and sinusoidal web under distributed loading are modeled with using ABAQUS finite element software, then the best waveform of the web is presented by comparing their resistance. . Also, the resistance of this type of girders has been investigated as one-span and two-span. In the recent study, the amount of steel used in all the samples is constant and the type of distortion, the distortion distance and the thickness of the plate girders web are variable. By studying and investigation all the numerical models, the most optimal shape will be presented among them.
