Corrosion imposes the biggest threat to steel structural integrity and coating has been widely used as a corrosion protection for steel structures. As coating itself can deteriorate over time, other strategies such as using better-corrosion-resistant steels (i.e., weathering steels) can be adopted. A recently developed stainless steel described in ASTM A1010 has shown better performance than the conventional weathering steels particularly in harsh environments. Considering some of the corrosion management strategies (such as high-performance coating and A1010 steel) have expensive up-front costs, they may reduce or eliminate the corrosion–related maintenance during a structure service life. Life-cycle cost (LCC) analysis is the appropriate tool to determine the economic benefit of corrosion management alternatives. The aim of this study is to compare LCCs of various corrosion management strategies. Especially, two steel structures are considered: a truss bridge and a bridge girder, using either coated conventional carbon steel or A1010 steel. For the coated carbon steel structure, a new corrosion model considering both coating degradation and corrosion effect on the steel is proposed and thus the time-dependent performance is assessed using reliability analysis considering uncertainties. LCCs are then calculated based on the initial costs and corrosion related maintenance costs. The results show that A1010 steel may be economically beneficial over the conventional coated carbon steel, but it depends on the parameters used in the LCC analysis, such as the maintenance strategies adopted, the environment, the discount factor, and the type of structure.
