Abstract |
This paper summarizes the results of a research on the isolate effects and economical efficiencies of seismic isolation design compared with the existing earthquake-resistant design, and presents seismic performance of the base isolation system consisting of sliding-type bearing and lead rubber bearing (LRB) compared with that consisting of the LRB only. From the results of the research, it is verified that seismic isolation is very effective to mitigate the influence of earthquake on structures and it is possible to increase the serviceability due to decrease of the floor acceleration. Also, from the point of view of reduction of story acceleration and base shear, the base isolation system consisting of sliding-type bearing and LRB is more effective than that with LRB only. In respect of economical efficiency, special care should be taken in using this method since costs which have to be paid in proportin to increased performance are high.
