콘크리트 재료모델에 따른 철도차량 일탈방호시설물(DCP)의 충돌해석적 검토

초록

This paper has developed a Derailment Containment Provision(DCP) between rails to prevent derailed accident of the train. And developed DCP under impact loading was analytically evaluated using LS-Dyna. This paper was simulated using Mat_72R3 and Mat_CSCM for concrete material. To modify the developed DCP, this paper was suggested suitable and reasonable analytical concrete material model.
