The ecological changes in the ocean due to the drastic global warming require that action be taken to sustain the productivity of fisheries. Proper ocean facilities could help prevent the loss of the expenditures made on marine aquaculture and reduce the related compensation for various ocean conditions. The aim of this study was to develop a floating ocean wave-breaker using an eco-friendly concrete and conducting a site survey, a structural analysis, and a test of towing the tank. As a result, the wave at the fish farm would be reduced. The results of the holding power of anchors and the capability of moving the floating structures were considered in the design of the wave-breaker. The analyses of the material properties of concrete and the steel structures, as well as the CAPEX and OPEX analyses of the manufacturing and operation processes confirmed the superiority of the floating concrete wave-breaker. In particular, this study demonstrated that the concrete floating breakwater can protect the fish farm against typhoons and reverse-waves, thereby reducing losses of the fish.

연구목적: 본 연구는 콘크리트와 PE(Poly Ethylene)로 구성된 부유식 방파제 모듈 간 결합을 위해 케이싱형 전단키를 제안하고 구조성능을 평가하였다. 연구방법: Eurocode에 준거하여 전단키 유형별로 극한 하중 실험을 수행하였다. 연구결과: 케이싱형 전단키가 무근 콘크리트 최대 전단 저항력을 개선(무근 전단키 대비 1.5배)하는 효과를 보였으며, 철근 콘크리트 전단키 대비 최대 전단 저항력 이후의 연성 거동을 증가시키는 효과를 나타냈다. 결론: 제안된 케이싱형 전단키의 활용을 통해 모듈형 구조체 간 전단 연결 안전성을 향상할 수 있을 것으로 판단된다.
