In rack system, the beams are generally boxed cross-section, and columns are open thin walled perforated section to accept the tabs of beam end-connectors. In storage racks, hook-in end connectors are used to make beam to column connections. The semi-rigid nature of this connection is primarily due to distortion of the column walls, tearing of the column perforation, and distortion of the beam end connector. The structural behavior of storage racks for seismic loads depends on how the individual components like beam to column connections, column bases and members perform interactively with each other and therefore, it is important to have a proper way of predicting the structural behavior of storage racks systems under seismic load. The complete 2 -D and 3 -D finite element model of conventional pallet racking systems were prepared using the finite element program ANSYS. Free vibration modal analysis and spectrum analysis carried out on pallet racks with the 18 types of column sections developed along with semi -rigid connection . The principal aims were to find out fundamental time period, mode shape and response to the spectrum acceleration of conventional pallet racking systems, made up of cold form sections. Parameters selected for study are cross section of uprights, thickness of uprights, and stiffness of the connections. KEY WORD : Dynamic analysis , pallet racks, cold formed steel, semi rigid joint
