Shear Behavior Analysis of Steel Plate Girders with Local Corrugated Web under Monotonic Loading

Plate girders are flexural members and they usually use instead of hot rolled sections in the matter of their high flexural capacity. Plate girders are made by suitable combination of steel plates the reason why monitoring of shear stresses in plate girders with thin-walled webs are important is the probability of shear buckling and failure of web due to the initial steps of loading. Experiences illustrate that if intermediate and bearing stiffeners used in plate girders, not only the shear buckling do not cause failure but also it stay stable for bearing loads. The main objective of this research was study on their behavior of plate girders with corrugated web in comparison with plate girders with bearing stiffeners due to controlling of shear buckling (local corrugated web created by applying incremental static loading). In this research several items got studied like how to create local corrugated web and their properties and performances in shear buckling large deformations and some analytical methods like numerical buckling analysis. Results provides information about the higher shear capacity in plate girders in local corrugated web in comparison with simple plate girders without any stiffeners.
