Hybrid System Device for Seismic Isolation of Structures (original) (raw)
Abstract
The research presented in this scientific paper investigates an adaptive seismic isolation system meant to protect building structures subjected to a variety of seismic ground motions. This scientific paper presents a solution that is adequate for the seismic isolation of small buildings, bridges or viaducts, having main dimension less than 10 meters. The solution proposed by the authors is one of a composed type. The isolation system consists of sliding isolation bearings in combination with fluid viscous damper devices. The results of the research have revealed a favorable characteristic of this isolation system. The proposed system is therefore capable of simultaneously limiting the response of both sliding base isolation system and superstructure, for a large variety of seismic ground motions.
