“…The this very important aspect and propose verification approaches that do not adequately account for the effects associated with warping torsion and with the non-coincidence of the shear center and the cross-section centroid. It is worth noting that several studies have been developed on selective pallet racks [1,2], while more limited attention has been paid to drive-racks [5][6][7][8]. There is no research dealing with the response of beams in industrial storage systems, nor do key features of their response seem to be adequately accounted by the most recent rack design codes.…”

SUMMARYThe paper deals with the effects and costs of implementing a base isolation system for the mitigation of the seismic risk of an existing steel rack structure. Different realistic distributions of the payload mass and occupancy levels, which form different plan asymmetric variants, have been analysed. The results obtained by the pushover analysis (N2 method) are presented as top floor envelopes and as plastic hinge damage patterns. In the presented cost study, the cost of the implementation of the proposed base isolation system is compared with the estimated costs of structural repairs to the damaged structural members of the superstructure, as well as with estimated expenses of the downtime period. The results have shown that base isolation is, in general, not economically feasible for lower ground motion intensities, whereas it could be of great benefit in the case of moderate and high intensities, especially if the downtime period is taken into account. 409-15 RESUMEN

“…In the down-aisle direction (longitudinal direction), the frame is normally designed as a moment resisting frame. Since steel storage racks are typically unbraced in the down-aisle direction, the stability relies heavily on the beam to column joints and the connection at the point of base plate (Freitas et al 2010). It was found that the capacity of energy dissipation and ductility for storage racks is much greater in the down-aisle moment-resisting direction in comparison to cross-aisle braced frame direction (FEMA 460 2005).…”

This paper describes the behaviour of selective steel storage racking systems in the cross-aisle direction. Steel storage racks are regular kind of equipment; these systems are developed for enhancing the storage of load units in diverse weights and sizes. In most cases in this study, the boundary conditions assumed fixed on their fundamental state, to prevent from any possible moment -rotation and uplift effects on uprights. Finite element method (FEM) modeling was used to analyze and evaluate the natural frequency of diagonally k-braced frame at cross-aisle direction. This report takes advantage of capabilities of two well-known structural analysis software for FEM modeling: Abaqus and Strand7. The objective is to predict and determine the eigenvalues and natural frequencies of selective steel storage racks in the cross-aisle direction. Taking the fact into account that the reaction of the structure under seismic loads is vitally important at this critical direction, this paper will provide a better view for designing these type of structures in the future. The novelty of this paper is to classify conditions where we could avoid creating any possible resonance in the structure.
