摘要：	Weathering steel sign structures are widely used in interstate highways and at traffic intersections. They are susceptible to fatigue, cracking and lateral buckling under wind loads because of their high span-to-weight ratio and relatively small cross-sectional area. State Departments of Transportation (DOTs) need to consider rational and viable decisions regarding preservation and replacement alternatives of weathering steel sign structures. The decision-making and prioritization of maintenance and replacement plans can be executed more objectively when a representative framework is developed. The ultimate goal of this project is to assist the West Virginia Department of Highways (WVDOH) in managing its weathering steel sign structures inventory through appropriate periodic inspection and evaluation of their current condition. To achieve this goal, the researchers developed an element condition rating system and an overall sign structure inspection framework. This framework was then applied to the WVDOH inventory in its Charleston Interstate System, which includes 82 weathering steel sign structures.
