Stability of rack structures

Evaluation of connection flexibility in cold formed steel racks

“…Quite a few numbers of tests were reported in the various different types of connectors in the pallet racking system. Lewis [6] provided a simple design approach to the stability of pallet rack structures and the effect that the form of the moment-rotation characteristic has on the type of stability exhibited by the system. Markazi et al [7] conducted tests on the four different types of commercially available beam end connectors to determine the parameters governing an efficient beam end connector.…”

Modal analysis of cold-formed pallet rack structures with semi-rigid connections

“…Lewis [5] worked on the down aisle stability of rack structures. In his analysis, a single internal upright column carrying both vertical and horizontal loads was used.…”

Numerical study on semi-rigid racking frames under sway

“…The main components of the structure are the uprights (columns) which are open thin-walled sections perforated to accept the tabs of beam-end connectors; the beams are often in the shapes of channels, hat-sections or rectangular boxes [1,2]. Investigations into rack structures have been made by various authors [2][3][4][5][6]. Davies [2] and Lewis [3] were primarily concerned with the stability of the structures.…”

“…Investigations into rack structures have been made by various authors [2][3][4][5][6]. Davies [2] and Lewis [3] were primarily concerned with the stability of the structures. Previous work by the authors [4,5] used a single column model in conjunction with stability functions to analyse rack structures.…”
