철도 구조물의 시스템 신뢰성

초록

Recently, the railroad which is spotlighted to one of alternative plans for green growth and decreasing CO₂(carbon dioxide) has seen remarkable improvement in its speed and the development is still under way. But, the development of design, safety evaluation and definition of performance for railroad structure have not been researched as well as speed improvement for rolling stocks. It is needed to improve existing evaluation method which is subjective and qualitative to objective and quantitative evaluation method for railroad structure. For this, system reliability analysis is expected to give an effective solution. In this paper, It is suggested the example of system reliability evaluation for railroad structure by using general ways. and It is expected that it would be helpful to find the advanced and objective way to evaluate performance of railroad structure.
