건축구조물 지진 격리 장치의 현황 및 적용방안

The fundamental principle of seismic isolation is to modify the response of the building so that the ground can move below the building without transmitting these motions into the building. A lead rubber bearing is formed of a lead plug force-fitted into a pre-formed hole in an elastomeric bearing. The lead core provides rigidity under service loada and energy dissipation under seismic loads. In this paper, engineering properties and performance evaluation for seismic isolation as lead rubber bearing will be introduced.
