Nonlinear Stability Analysis of 2-D Cold-Formed Steel Storage Rack Structures

Industrial storage racks are among the most important structures made from cold-formed steel sections. This paper deals with linear and nonlinear stability analysis of a pallet racking system. The main focus of this study is to ascertain the stability of 2-D frames of a pallet racking system. With this objective, pallet racking system with cold-formed steel section is simulated by 2-D models using shell elements in ABAQUS. Linear and nonlinear stability analyses are carried out on these frames. The results are obtained from FE analysis of frames with 12 types of column sections are presented in this paper.
