Abstract

During an earthquake, there are two main effectual factors causing damage to structural and non-structural members; The two factors are relative lateral displacements of stories (drift) and absolute acceleration of stories. In this study, seismic isolators have been considered as a solution for dealing with damages and their causing factors, because they can both decrease the relative lateral displacements and absolute acceleration of stories significantly. Consideration of a 5 story building which was modeled in ETABS software, showed that using a system of lead rubber bearing base isolator (LRB) can significantly reduce the relative displacements and shear forces of stories (on average, about 50%); so the structural design leads to the optimal degree
