전세계적인 인구증가와 산업화로 인하여 육지면적의 부족, 육상자원의 고갈 등의 문제로 해양의 이용 및 개발의 관심이 늘어나고 있으며, 환경친화적인 해양공간을 확보하기 위하여 초대형 부유식 해상구조물에 대한 기술개발이 요구되고 있다. 본 논문에서는 초대형 부유식 구조물의 상부구조물에 대한 시간이력해석법에 대하여 소개하고 파랑하중에 의한 부체변형을 이용한 시간변위이력 산정 방법을 제안한다. 또한 주기 및 진폭의 변화에 따른 상부구조물의 동적 시간이력응답 결과를 분석하고 초대형 부유식 상부구조물 시설계안의 동적구조안전성을 평가한다.

The planning process of complex projects in oceanic architectural engineering is characterized by the cooperation of many involved specialists and by a high degree of information exchange. In order to improve the quality of the structural design of oceanic buildings, information of different involved partners in the planning process has to be integrated. This paper aims to introduce a concept of the integrated structural design for the floating-type oceanic building using STEP(Standard for the Exchange of Product Model Data). STEP(ISO 10303) is an international standard for the computer-interpretable representation and exchange of product data and it provides a consistent data exchange format and application interfaces between different application systems. In this paper, the structural design process and information of oceanic buildings is analyzed and product models are preposed fir the exchange of the structural design information between superstructure and floating structure. The entities for calculating wind loads, metacenter and restoring forces are represented by Express. As a case study a floating hotel is applicated to describe the STEP physical file.

In this thesis the legal systems related to real estate and sea area utilization are studied in order to improve them for construction of Very Large Floating Structure. Main research subjects are as follows: 1) Whether can Very Large Floating Structure be accepted or not as real estate like house and land\ulcorner 2) How can the sea area which is occupied by Very Large Floating Structure be utilized\ulcorner As the conclusion, the Very Large Floating Structure can be registered as real estate even though it is not specified by Korean law for the present. The design concept of Very Large Floating Structure can be interpreted as satisfying enough necessary conditions and factors for Very Large Floating Structure to become real estate. In the near future, we have to make improvement on the laws related with the construction of Very Large Floating Structures so that private sectors can joint the construction. In additions, a new law for various floating structures should be made as soon as possible.
