lower than its vertical stiffness. If this lower (lateral) stiffness is comparable to the stiffness of isolators, it certainly affects the overall stiffness and thereby the response of the machine-foundation system. Hence, the lateral stiffness of the support structure must also be computed and considered while selecting the isolators.
