Abstract
In the last decades, steel girders with corrugated webs have been widely investigated and implemented in many applications such as bridges and industrial facilities. Many researchers investigated the flexural behavior of traditional doubly symmetric girders with corrugated webs, but a very limited number of investigations considered the usage of unequal flanges. In addition, for most cases the performed investigations focus on the behavior of large-scale girders similar to bridge girders, while few papers considered small-scale girders that could be used in traditional structures. Thus, the objective of this paper is to investigate the lateral torsional buckling behavior of small-scale unsymmetric or monosymmetric girders with corrugated webs (MSCWGs) as increasing the compression flange dimensions is a common solution to enhance the lateral torsional buckling rigidity of steel girders. A finite element model is established and verified using ABAQUS software. Then, using the verified model, a series of finite element models are developed through a parametric study to investigate the effects of varying the length, compression flange dimensions and web height on the behavior of MSCWGs. Finally, the current available expressions to calculate the critical buckling moment of MSCWGs are evaluated and the investigation conclusions are outlined.
