This paper deals with the response analysis of a floating building structure subject to both wind and wave loads. The hydrodynamic analysis is performed with sets of wind and wave loads selected from the 100-year return period concept to assess the effect of extreme ocean environmental loads on a floating building. From hydrodynamic analysis in time-domain analysis, it is shown that the responses obtained from the analysis in consideration of both wind and wave loads are far greater than those of wave load only.

According to climate change, deficiency of usable land, large water portion of the Earth surface, and improvement of income level, floating architecture is emerging as a strong & attractive alternative. The aim of this study is to suggest some related applying ways for new building projects around waterside. New paradigm of architecture can be described as a new model and/or system of architecture with new concept and Zeitgeist like sustainability and green building. Floating building is already a new paradigm of architecture comparing with the preconception of building only on the land and current building regulations. New paradigm features from the sample projects can be summarized as new concepts of building, application of various renewable energy resources(water, solar, wind), modular construction, use of local raw material, dual purpose usage, long term and relocatable usage, and special building materials for green building.

최근 해상을 비롯한 수상공간에 다양한 플로팅 건축물이 계획되거나 설치되고 있다. 그러나 관련 법제도의 미비로 인하여 플로팅 건축물의 설계 및 건설 혹은 관리운영에서 많은 문제점이 발생되고 있으며 이는 플로팅 건축물의 활성화를 저해하는 중요한 요인이 되고 있다. 따라서 본 연구에서는 플로팅 건축물에 대한 국내 법제도 적용 사례 및 해외 관련 법제도 사례 조사를 실시하여 우리나라에서 플로팅 건축물의 법제도 개선을 위한 기초자료와 개선방향을 제시하였다. 연구결과 플로팅 건축물은 선박이 아닌 건물로서 법적 지위를 확보하며 플로팅 건축물 설치 특별구역을 설정하여 건물의 대지를 조성하고 별도 기술기준을 적용하며 건축인허가 및 등기 절차를 활용할 수 있도록 법제도 개선이 필요하다.

According to the climate change and the improvement of income level, floating building on water has been emerging as a strong alternative. This study was intended to suggest some reference materials of sustainability for new floating building projects. The concept of sustainability and floating building was investigated, and 3 realized projects and 3 planned projects were reviewed in terms of sustainability. Sustainable features of the sample projects can be summarized as recycled and relocatable usage, adoption of various renewable energy techniques, installation of self-supporting plant, application of modular system and others like new material & open layout. Sustainable features need to be developed more and more in detail and applied to many types of floating buildings.
