Seismic Response of Asymmetric Sliding Steel Structure with Considering Soil-Structure Interaction Effects

One of the methods of resisting to earthquake forces and its undesirable effects on structures is the use of seismic isolators. Investigations on the seismic structure have been initiated by researchers since decades, but so far no study has been done on the subject of this research. Therefore, in t...
