Abstract
This paper investigates a new device called oval leaf spring mounts (OLS) to protect sensitive equipment from external source vibrations. The main outcomes of this study are to represent the cyclic force-displacement from finite element analyses by the Bouc-Wen model of hysteresis which permit to identify the required parameters for further seismic analyses. The performance of the device through its implementation into a cooling tower mounted in the rooftop of 8th story structure was evaluated. The efficiency of the device under several earthquakes was investigated. The obtained results from seismic analyses have shown the ability of the OLS device to reduce the seismic input sufficiently in the cooling tower without significant displacement and in both horizontal and vertical directions.
