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.

본 논문에서는 TV 주파수에 있어서 건조물에 의해 발생하는 전자파장해를 평가하기 위해 건축물 주위의 산란전자계를 수치계산하였다. 건축물 외벽에 전파흡수체를 부분적으로 부착한 경우 콘크리트면의 노출면적과 반사전계강도와의 관계를 조사하였다. 계산된 산란 전자계로부터 DU 비를 구해 TV 고스트방지를 위하여 건축물 외벽에 부착할 전파흡수체에 요구되는 반사 감쇠량을 구하였다.
