Experimental Seismic Response of Base Isolated Pallet-Type Steel Storage Racks

This paper presents the results of uniaxial and triaxial shake table tests performed on directly anchored and base isolated steel pallet storage racks loaded with simulated and real merchandise. The new base isolation system provides seismic isolation in the cross-aisle direction of a rack only, while providing similar restraints as conventional bolted base plates in the down-aisle direction. The objective of the isolation in the cross-aisle …
