The effectiveness of the floor isolation of block type rigid equipment is investigated using seismic fragility curves. A floor isolation system is proposed for the equipment. The equipment is considered in three different conditions referred to as; ``equipment on the ground'', ``equipment on the building floor and without floor isolation'' and ``equipment on the building floor with seismic floor isolation''. The seismic fragility curves are calculated for each case to evaluate the vulnerability of the equipment to rocking motion and toppling. Different aspect ratios are considered for the equipment. The results of the study on the rocking response of the equipment during earthquake show that floor isolation is effective in reduction of seismic fragility of the equipment on the floor, compared to the non-isolated equipment. Furthermore, the vulnerability of similar equipment increases with a reduction in aspect ratio.
