강관파일그룹의 선박충돌해석 = Ship Collision Analysis of Steel Pile Group

다국어 초록 (Multilingual Abstract)

The ship collision analysis of steel pile group as protection system of bridge in navigable waterways is performed to analyze the dynamic characteristics of that during ship-protection system collision. The analysis encompasses finite element modeling of ship and pile, modeling of material nonlinearity, hard impact analysis, displacement-based analysis and soft impact analysis etc. Through the analysis of hard impact with a rigid wall it is able to grasp collision load, displacement, etc, depending upon collision type of ship bow and to inspect validity of ship model. In the displacement based analysis it is able to confirm the part that plastic hinge is generated and to estimate a rough range of energy that protection system can absorb within its maximum horizontal clearance. In the actual collision analysis it is able to know dynamic behavior and energy dissipation mechanism caused by interaction between ship and protection structure.
