Industrial racks are normally framed structures fabricated from cold-formed sections and relative to their self weight (Dead Load) carry very high Pallet Loads (live load) compared with conventional civil engineering structures. Lack of sufficient design rules and specifications provides an urgent need to better understand their performance under seismic loads as well as static load. Due to their slenderness controlling sway deformation is an important factor in the design of industrial racks and hence special attention must be given to factors such as ‘beam to upright connections’ and ‘base plates connections’. This paper focuses on theoretical approaches to perform stability analyses of storage rack structures and considers the effects of incorporating the stiffness of baseplates and bracing elements in the critical buckling load. Also the effect of cyclic moment rotation deterioration on the global stability of the frame is highlighted. A stability limit has been defined for a maximum pallet load to be stored on a particular rack structure.
