Abstract
Further maintenance should be conducted for pier due to its vulnerability towards chloride induced deterioration. However, research for residual structural performance and seismic performance of corroded pier is still limited. Since significant cost and time is needed for regular detailed survey to evaluate the residual structural performance of corroded pier, relatively simple evaluation method becomes necessary, especially for private businesses. In this research, load tests for specimens with different deterioration degrees are conducted, relationship between deterioration degree and residual structural performance is clarified. Introducing the results of the tests to versatile structural analysis software, simple evaluation method of residual structural performance is proposed. By reflecting the judgment result of deterioration degrees of a real corroded pier to structural analysis model, seismic damage area and level could be relatively easily and quantitatively shown.
