Finite Element Simulation of Cold Formed Steel Stiffened Zed Sections for Local, Distortional And Lateral Torsional Buckling
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 1
Abstract
The aim of this paper is to be to explore the post-buckling behavior and ultimate strength of cold-formed steel (CFS) stiffened members in bending. The Finite Element (FE) models provide a supplementary tool to verify the design methods as well as to explore the buckling mechanism of cold formed steel members with various configurations. In this paper, the numbers of finite element models areestablished using ANSYS software for both stiffened and unstiffened elements. A particular emphasis has been given to the study of strength and behaviour of different cold formed steel zed sections with flange or web intermediate stiffeners. Cold formed steel members can be plain in simple applications, but if provided with flange or web stiffeners, their performance and resistance to local, distortional and lateral torsional buckling improves. The idea behind this paper is to use cold-formed steel members with modifying the shape rather than thickness to support load. Due to the relatively easy method of manufacturing, a large number of different configurations can be produced to fit the demands of optimized design for both structural and economical purposes.
