A study on the evaluation of structure damages for the visual inspection

The structure inspections are to check out safety problems of the public facilities and to ensure a high level of safety for all users. Generally, the initial inspection of concrete structures is carried out using visual inspection. These methods are qualitative and based on empirical knowledge. There are few data and useful system for supporting visual inspection. The goal of this paper is to evaluate structure damages for the visual inspection, for developing the computer aided system of the deterioration diagnosis of concrete structures. This system is based on Kansei engineering since the concrete experts have such kinds of human feelings (Kansei) of "safety". Kansei engineering is able to transfer feelings to the field of visual design. We could obtain the databases of diagnosis information to identify the relationship between the structure damage and expert estimation. The structure inspectors are able to ensure high safety of structures using this information.
