Analytical Study of Shear Buckling Behavior of Trapezoidal and Sinusoidal Corrugated Web Girders

In this study, nonlinear finite element analysis was performed in order to identify the effects of variables that compose sinusoidal webs, and to analyze the effects of the ratio (β) of the length of the horizontal panel to the length of the tilted panel, one of the variables that compose trapezoidal webs. Based on the analysis models with high accuracy that were validated by earlier studies, variables were analyzed depending on the shape of webs. In addition, equations suggested by earlier studies were analyzed based on the validated models using the results of the analysis of variables. It was found that the equation in Eurocode is more conservative than other equations suggested by earlier studies.
