한계상태설계법에 기초한 강박스거더교 내하율 평가

다국어 초록 (Multilingual Abstract)

This study proposed an modified load-bearing capacity evaluation method based on LSD(limit state design) - the current bridge design codes. It is possible that the improvement validated in the load test be applied to this method. From the results of evaluation of 32 bridges in service, analysis and comparison are made on rating factors found by ASD(allowable strength design), LSD and improved LSD. The results of the 3 methods show high interrelation. This interrelation is expected to provide a method to convert rating factor found by ASD to a rating factor found by LSD.
