Flexible Concrete Mattress 보호구조물의 앵커 충돌 수치 시뮬레이션을 위한 기초연구

Abstract

The purpose of this paper is to provide a fundamental data for anchor collision simulation of a FCM(Flexible Concrete Mattress). For this reason, numerical models according to material model(elastic-perfectly plastic model, Drucker-Prager model and RHT concrete model), finite element model(existence of reinforcement bars) and load condition(collision angle and falling distance) were compared. The results show that the RHT concrete model is the most suitable for this simulation. And the FCM has to be mrodeled by RC concrete for more accurate collision simulation. The critical condition of anchor collision is that the anchor haven’t collision angle.
