의사결정방법에 의한 교량의 상태 평가

Abstract

In this study, a method based on the Analytic Hierarchy Process for systematizing the maintenance and securing the safety of the reinforce concrete bridges using an appearance inspection and state evaluation was proposed. It would be possible for general structure engineers to appraise the bridges with this method. Results from periodical inspections are mostly qualitative because of the inspector's subjective judgment. Therefore, for more objectivity of the results from the safety inspections, quantitative standardization processes of the appraisal items areessentially required. Properties of the selected items were standardized with reference to the existing research results and actual data. As for the item thatis difficult to represent quantitatively, word variable of the Analytic Hierarchy Process was introduced and standardized so that the objectivity of the subjective valuation was acquired. Results from this study are as followed. It is possible to acquire very reliable appraisal results of the reinforce concrete bridges according to the Analytic Hierarchy Process defined in this study. Result from this study can be applied practically through the application and analysis of the appraisal technique and the procedure with actual data. Verification through the practical uses and improvements are required for the development in this field.
