Seismic simulation tests on sloped rolling-type isolation devices with different design parameters such as sloping angles and supplemental sliding friction capabilities, together with a isolated raised floor system were conducted in this study. Not only is the efficiency of the isolation devices in seismically protecting the objects studied, but also a validation of the derived theory in predicting the seismic responses of the isolation devices is experimentally investigated. From the study, it is evident that the sloped rolling-type isolation device has excellent potential for the mitigation of seismic risks posed to critical equipment and facilities. |
