Abstract

This academic article is the study of numerical model using the ordinary type and the boundary condition type Finite Strip Analyses for stability analysis of the cold-formed structural steel. Since the thin cold-formed steel results in the complication of stability problem of elements especially for some very complex bucking formats. The models for the cold-formed steel beam of Hat Shape section of the Grade Designation steels of G550, G360, G350, and G300 have been studied for the correlation. In addition, the deformations occurred by key limit states in all three types, which are overall buckling, distortional buckling, and local buckling are also investigated by using the CUFSM Program, in order to calculate the “Direct” Strength and compared the analytical results from the Finite Strip method with the experimental results from the laboratory. The outcomes of this study are to compare the power of direct blending of the beam which was designed as shown in the theory; ASD, LRFD and LSD. To compare the power of direct blending of cold-formed steel by FSM method and the outcome of actual test in order to perform the design of Thin-Walled Structures.
