ABSTRACT
The members of bridge have a mutual correlation in which one replacement can trigger another replacement. And thus, a system level maintenance scenario would be a realistic proposal as it simultaneously considers maintenance interventions in each member which consists of bridge system not a simple combination of optimum maintenance scenario in each member. Therefore, this paper discussed the generation of optimum maintenance strategy in the system level considering the members which consist of the bridge as well as in the member level, and studied more practical and rational method through the comparison of analytical examples between different levels. It also dealt with the feasibility of the optimum maintenance
strategy considering its limit in the real situation by applying the proposed method.
