EVALUATION OF LEVEL-ONE GROUND MOTION AND PERFORMANCE VERIFICATION OF GRAVITY TYPE QUAY WALLS

Abstract

This paper aims at presenting the examples of the level-one ground motions for port and harbour facilities. Authors proposed a new framework for seismic hazard analysis considering source, path and site amplification effects especially due to the deep subsurface profile. Level-one ground motions as time histories were calculated for 23 ports by this method. It is shown that PGA and PGV for each port differ a lot although regional seismic coefficient is classified into only 5 categories in the current design method. Authors also evaluated the difference of earthquake response of gravity type quay walls
