Case study: LCC analysis for Krk Bridge

The Krk Bridge (constructed between 1976– 1980) connects the mainland and the island of Krk, and consists of two arches including one of the largest conventionally reinforced concrete arch span in the world. During more than 25 years of service the bridge was exposed to very aggressive environment which caused corrosion problems. Therefore, structures of both arches are being repaired intensively during last 10 years. In this paper approximate costs of the maintenance and repair works performed during last 3 decades on the small and big arch of the Krk bridge are analysed. The actual costs are compared to the estimated costs of the life cycle management, if outer layer of carbon steel reinforcement had been replaced with stainless steel.
