Abstract:
Abstract: Several bridge management systems (BMS) have been developed to estimate the future expenditure for
bridge management, but those have not been sufficiently applied to the practical bridge management for the reason
of complex problem that the damaged bridge members should be repaired at one time as much as possible
considering the whole bridge system. In this study, a useful BMS for practical bridge management is developed
without special techniques. The deterioration transfer curves for slab, girder and abutment are introduced for three
classifications of rapid deterioration, standard deterioration and no degradation members. The most economical
repair plan is determined by comparing the life cycle costs for nine cases considering the annual budget limit. The
effectiveness and practical usefulness of the system are illustrated by applying it to the bridge management of 1381
bridges in Fukui city, Japan.
