Proposal of Method of Selecting Structure that should be inspected by Priority based on Repair-Risk

Abstract

In this paper, in order to evaluate the influence of dispersion of quality of concrete cased by construction errors on the maintenance management of concrete structure quantitatively, Repair-Risk was proposed. Repair-Risk was calculated by using the prediction result of deterioration of concrete structure considering with the dispersion of quality of concrete and the risk curve of repair cost. Even when two or more structures should be managed, the inspection plan (selection of inspection item, evaluation of the effect of accuracy of inspection method and selection of structure) can be made by using proposed method.
