Optimum Safety Indices Based On Expected Total Cost Minimization

총기대비용 최소화원칙에 의한 최적신뢰성지수

The safety factors of current standard code are considered to be not appropriate compared to design and construction practices, even this safety factors are not determined from probabilistic study but merely from experiences and practices. This study pripose the optimum safety indices based on expected total cost minimization using only three parameters, which are the level of the failure cost to the initial cost by improvement in safety, and the order of the initial cost function.
