In order to evaluate margin quantitatively included in the analysis method of the rules on fitness-for-service, potential factors which may have effect on collapse load were identified and the probabilistic distribution of collapse load caused by the variation of these factors was calculated. The margin was evaluated quantitatively by comparing the probabilistic distribution of collapse load with the allowable limits calculated by the existing analysis method of the rules on fitness-for-service. This study presented approaches to a rational integrity evaluation method on the rules on fitness-for-service based on the quantitative margin evaluation.
