Abstract

This paper proposes a method of estimating safety, reparability and usability of a building from the viewpoint of seismic risk evaluation. The seismic risk curves regarding the loss, which have been estimated in general, were assumed to show reparability. The effects of the interrelationship between the earthquake motion and the building response characteristics on the seismic risk were analyzed in detail. In the result, it was found that the magnitudes and relative ratios of seismic risk in the structural frame, drift-sensitive and acceleration-sensitive non-structural components were affected strongly by the interrelationship. This would mean the necessity of estimating seismic risk from the various points of view. The estimation of safety and usability was easily examined, but further study is necessary. Finally, one simple example of performance-based seismic evaluation of building based on the seismic risk evaluation was shown.'.
