MODEL TEST AND ANALYSIS ON THE EFFECT OF LONG-PERIOD AND LONG-DURATION GROUND MOTION TO BEHAVIOR OF QUAY WALLS

Abstract

Design input earthquake motions considering influence of characteristics of earthquake source fault and soil deposit are being used in seismic design of structures in recent years. It is becoming necessary to examine the behavior of the structure under ground motions with period and duration property which had hardly been taken into consideration. A series of gravitational and centrifugal model tests was conducted in this study, to investigate influence of long-period and long-duration earthquake motion on gravity type quay walls. Applicability of the finite element analysis, FLIP, to long-period and long-duration earthquake motions is examined by comparing the results of analysis and tests.
