STUDY ON ESTABLISHMENT OF BMS IN CONSIDERATION OF DAMAGE LEVEL, LIFE EXPECTANCY, USER COST AND THE VALUE OF BRIDGE STRUCTURES

Abstract

The purpose of study is to investigate the BMS in consideration of damage level, life expectancy, user cost and value of bridge structures. The damage level is carried out by analytic hierarchy process. The life expectancy is obtained by application of reliability analysis. UC is calculates from traffic assignment problem, and re-constructing cost is carried out for bridge value. The repair priority order of BMS is given by data envelopment analysis (DEA) from these parameters. It is considered that the analytical results are almost proper from these parameters. These analytical processes in this study have possibility of application for new type BMS in the future.
