キーワード：carbon steel reinforcement, corrosion, failure probability, life-cycle cost, RC structure, stainless steel reinforcement
Application of life-cycle cost (LCC) analysis is rapidly increasing that enables optimal decision on rebar type when designing reinforced concrete (RC) structures in a marine environment. In the present paper, it is concentrated on the LCC estimation of RC structures taking into consideration the rebar types and uncertainty associated with the prediction of chloride-induced corrosion. In an illustrative example, effect of the difference of marine environment (i.e. region and distance from the coastline) on the LCC and time-variant probability associated with the concrete cover cracking is investigated.
