Abstract

In the case of precise safety inspection and precise safety diagnosis of a building, a condition evaluation must be conducted to determine the safety grade. Since 2004, an evaluation method using fuzzy theory has been introduced for quantitative condition evaluation,and the relationship and importance of reinforced concrete members using fuzzy theory have been applied. Generally, fuzzy theory is a method used to deal with ambiguous expressions with unclear correlations, but at the time of development, it seems that it was developed by applying fuzzy theory as an alternative in a situation where inspection and diagnosis result data were insufficient. Therefore, it is necessary to verify the relationship and importance of evaluation items derived based on the current fuzzy theory using actual inspection and diagnosis result data.In this study, the correlation between the evaluation items was derived by using the results of 19 precision safety inspections and 9 precision safety inspections and the performance score function formula, and using this, a reasonable durability score calculation formula of the member was presented.

건축물의 정밀안전점검 및 정밀안전진단시에는 안전등급 판정을 위해 상태평가를 실시하여야 한다. 2004년부터 정량적인 상태평가를 위해 퍼지이론을 이용한 평가방법을 도입하였고, 퍼지이론을 이용한 철근콘크리트 부재의 평가항목 간의 관계와 중요도를 도출하였다. 일반적으로 퍼지이론은 상관관계가 명확하지 않고, 모호한 표현을 처리할 때 사용되는 방법으로, 개발 당시에는 점검 및 진단 결과자료들이 부족한 상황에서 대안으로 퍼지이론을 적용하여 개발한 것으로 보인다. 따라서 실제 점검 및 진단 결과자료를 이용하여 퍼지이론을 바탕으로 도출된 평가항목 간의 관계와 중요도에 대한 검증이 필요하다. 본 연구에서는 정밀안전점검 19건과 정밀안전진단 9건의 결과와 성능점수 함수식을 이용하여 평가항목간의 상관관계를 도출하였으며, 이를 이용하여 부재의 합리적인 내구성 점수 산정식을 제시하였다.
