Analysis and design of down-aisle pallet rack structures

This paper presents an efficient approach to the analysis and design of unbraced pallet rack structures subjected to horizontal and vertical loads. The structures are analysed by considering an equivalent free-sway column and solving the differential equations of flexure, including the P–Δ effect. Initial imperfections within the frame are allowed. Results of the analysis are compared with a traditional non-linear finite element solution of the same problem. The analysis algorithm is then incorporated into a design program, which performs code checks against global buckling, deformation and internal member forces.
