Assessment of seismic performance of an isolated structure equipped with a friction damper with coupling mechanism and an oil damper
https://orcid.org/0000-0002-4668-751X
In this study, a friction damper with a coupling mechanism (FDC) and an oil damper were added to the isolation layer of an isolated structure. Using the Kelvin collision analysis model, a time history analysis was performed by considering a possible impact in the isolation layer. Based on a comparative analysis of the seismic control effect, the following conclusions can be drawn. The combined isolation system proposed in this study gradually increases the attenuation performance of the isolation layer according to the magnitude of the earthquake by taking complete advantage of the FDC and oil damper and satisfies different performance requirements of the isolation layer of different magnitudes of earthquakes. In addition to the same control effect as the combined isolation system for seismic fortification intensity earthquakes, the best control effect can be achieved using a small control force for frequent earthquakes. Overall, the control effect on the acceleration of structural seismic response is pronounced. In the case of a rare earthquake, for not amplifying the seismic response acceleration of isolated structure, the maximum displacement of the isolation layer is controlled within the reserved safety range to avoid collision and damage between the isolation layer and surrounding maintenance structure.
