Introduction A series of full-scale shaking table tests were conducted at the University of Auckland Structures Test Lab. Three complete structures were tested in the cross-aisle direction, each with a different baseplate type: ductile, unanchored, and rigid (the former two allowing uplift and rocking response). The experiment aim was to determine the benefit, if any, of allowing the structure to rock in the cross-aisle direction. This was done by observing the rack displacement and upright axial loading up to the structural failure.
