Abstract

The purpose of this study was to analyze some parameters' effects on buckling behavior of Sinusoidal Corrugated Web using finite element analysis program. Studying buckling behavior is one of the most important things to design sinusoidal corrugated web girders and predict the shear performance. In this paper, Four parameters of Sinusoidal Corrugated Web, which are thickness($t_w$), height($h_w$), wave height(${\alpha}_3$) and wave length(w), were selected for buckling behavior analysis. Via buckling analysis, it is shown that $t_w$, $h_w$ and ${\alpha}_3$ have influence on shear buckling stress, Initial stiffness and reduced strength after buckling.
