Recently, the maintenance planning of prestressed concrete (PC) structures has been a significant problem and needed to be concerned. An appropriated structural maintenance is defined in order to minimize life cycle cost and extend the lifetime of structures with satisfied performance. This paper proposes an optimization method for maintenance planning of multiple prestressed concrete girders with considering multiple performance criteria and constraints. The girders are varied in environmental conditions, covering depth, number of tendons, etc. The performed criteria are durability, serviceability and load carrying capacity. Moreover, the constraint is maintenance budget. Therefore, member prioritizing, shifting repairing time or changing repairing method must be considered in optimization. It is shown that the annual repairing cost depends on the number of repairing time, unit cost of repairing, amount of damage and number of girder. The result of this study can be used for the decision making tool for planning budget of repairing work and prioritizing repairing prestressed concrete girders. Based on example given in this study, maintenance budget can be reduced for almost 30% within 50 years of service life.
