OPTIMAL RELIABILITY INDEX FOR PIER TYPE QUAY WALLS USING LIFE CYCLE COST ANALYSIS

Abstract

Optimal reliability indices were determined by life cycle cost analysis of pier type quay walls. Failure probability of pier and shore-bridge were investigated by response surface method. Then, they were used to obtain recovery cost after damaged. Costs for initial construction and maintenance were also considered in finding optimal reliability indices. Target reliability indices were suggested by numerical examples under seismic load and ship load.amaged.
