Steel bridges are usually prevented from corrosion by painting. In the corrosion prevention by the painting, a difference occurs in the performance by geographical environment and structural parts, and the painting has structural weak parts. As solution methods to reduce the difference, there are edge processing and partial repainting afresh of the weak parts. This study investigated lifecycle cost and lifecycle environmental impact when the solution method of the partial deterioration of the painting is used, and evaluated the lifecycle performance.
