Abstract

This paper presents the response calibration method based on quality control range, which is established from the concept and method of statistical quality control for natural frequency ratio and response ratio. To this end, statistical analysis including descriptive statistics analysis, normality test, ANOVA were performed for response characteristics obtained from loading tests and structural analysis for more than hundred and thirty well-conditioned bridges. Suggested method is based on real structural integrity evaluation case studies and statistical quality control approach, in this respect it is expected to provide scientific criteria and systematic procedure for response calibration and load carrying capacity assessment.

본 논문은 통계적 품질관리 기법을 활용하여 건전한 교량의 고유진동수비와 응답비 관리범위를 찾고, 그에 준거한 응답보정 방법을 제시하였다. 이를 위해 본 연구는 재하 시험 및 해석으로부터 도출된 구조형식별 정 동적 응답 특성에 대한 기술통계분석, 정규성 검정, 분산분석 등을 수행하였다. 제안된 방법은 실제 진단 사례에 근거하고 통계적 품질관리 기법을 활용함으로써 응답보정 및 내하력 평가를 위한 과학적 기준과 체계적 절차를 제공할 수 있을 것으로 기대한다.
