초록
본 연구는 실제 구조진단 사례에 기초하여 재료와 형식 및 공용기간에 따라 교량의 응답, 충격계수, 고유진동수 및 각 특성의 해석값/계측값 비 등에 관한 기술통계를 분석하고 주재료에 따른 T-검정과 구조형식 및 공용기간에 따른 분산분석을 통해서 요인 부집단 수준 간동질성 검정 및 다중비교분석을 수행하였다. 본 연구 결과는 응답 분포의 중심값, 산포도, 대칭성 등 통계적 특성 및 비교분석 집단 간 동질성 식별을 위한 참조값을 제공하며, 이것은 내하력 평가 등 구조 진단과 설계에서 엔지니어들이 취득한 계산 또는 계측값의 타당성을 비교검토하고 데이터베이스를 활용하는 등의 공학적 판단을 하는데 실제적으로 유용한 정보를 제공할 것으로 기대된다.
Abstract
This study tests homogeneity and performs multiple comparison analysis among treatment levels of each factor group throught-test by materials and analysis of variance by structural type and service period. For that descriptive statistical analysis isperformed for static and dynamic response characteristics and their ratios of calculated versus measured values based on a goodmany safety assessment reports for bridges. Homogeneity and post hoc test based on descriptive statistical analysis provide themeasures for homogeneity identification among comparison groups in addition to the statistical reference values such as centraltendency, variation and shape. This study is expected to be valuable for structural integrity assessment and design by comparingthe measured and calculated values with the reference values for the homogeneous group identified, which can help the engineersreview the adequacy of the values and put the group database to practical use.
