Analytical and Experimental Investigation of Cold Formed Steel Sections under Bending

The primary interest of this project is to study the possible buckling occurrence on various cold formed steel closed sections like Box section, front to front Sigma and front to front Z-sections used as beams. Since the flexural load carrying capacity of the above mentioned sections under bending varies greatly with respect to its shape. In order to study different load capacity initially, a reliable finite element model was generated using the ANSYS software package to predict the flexural load above mentioned cold formed structural sections and to obtain a better understanding of the buckling failure behavior. For this purpose, a finite element model was developed using ANSYS. Theoretical study is done by using Euro code (EN1993 Part1-3) to determine the buckling behavior. Experimental study is performed by testing the specimen under bending. The Experimental investigation, theoretical investigation by Euro code (EN1993 Part1-3) and numerical investigation has been compared and concluded.
