Appropriate maintenance should be conducted for harbor structures due to their vulnerability towards chloride induced deterioration. We have already proposed an evaluation method of residual structural performance based on the judgement result of deterioration by versatile structural analysis software. On the other side, a simple evaluation method without structural analysis is also demanded when deciding the maintenance priority of several piers. In this study, evaluation methods of residual structural performance introducing artificial intelligence to estimate the damaged area ratio towards assumed external force are proposed. The estimation accuracy of artificial intelligence models are verified and damage estimation for piers with random deterioration distribution are conducted. As a result, for both models utilized numerical information and image showed high estimation accuracy, and the image model can also grasp the damage distribution as well as the damaged area ratio.
