Fatigue Reliability Analysis of Bridge Structures
교량구조물의 피로신뢰성 해석연구
Abstract
The safe design against fatigue failure becomes more important criterion in highway bridges. The fatigue-safety evaluation is performed for the current bridge code. A reliability model incorporating fatigue damage is formulated and the satety indices are calculated. The present study indicates that the calculated safety indices vary greatly with traffic volumes and loadometer values. A method is proposed to maintain uniform reliability for vafious traffic conditions and loadings.
