  A study on seismic isolation of building used LRB

  Yurdakul, Muhammet; Yildiz, Burak

  Base isolation system with lead rubber bearing (LRB) is commonly used to preventstructure against to damage of earthquake. Design of LRB system is detailed in thisstudy. The isolated building with LRB design according to Uniform Building Code(UBC-97) and fixed building were examined. The six-storey building with LRB andfixed building were modelled in SAP2000 with the same dynamic loads. The relativefloor displacement and internal forces of the seismic isolated and fixed building arecompared. In addition, transverse and longitudinal reinforcement of any axis of seismic isolated and fixed building are compared. Analyse results showed that effectiveness of using seismic isolation system on building. The weight of longitudinal andtransverse reinforcement of isolated building is smaller than fixed building about36%, 40% respectively.
