도시철도차량 구조체의 수명평가에 관한 연구

초록

In these days, almost urban railway vehicle has been serviced under the random load application. But it is very important that fatigue life prediction for structures is major factor of safety. So do this, it is required that fatigue assessment method for cumulative damage approach while Korea domestic regulations only has endurance limit approach. With this endurance limit approach, fatigue life prediction is impossible. In this research, it will be present that fatigue assessment for urban transit structure by using of cumulative damage approach method and related theories.
