최근 해양개발에 대한 관심이 증가하고, 해양의 중요성에 대한 인식이 높아지고 있다. 이에 정부 차원에서 다양한 형태의 정책과 연구가 진행중이다. 이러한 해양개발에 필수적인 시설이 해양건축물이다. 따라서 이 연구에서는 올바른 플로팅 구조물의 설계법을 제시하고 또한 안전성을 평가할 수 있는 지침을 제안하였다.

With regard to smoke control system, the design guidelines of smoke exhaust for accommodation and smoke control for evacuation stairs and vestibule has been proposed domestically, but after reviewing the applicability to modern buildings that tend to be larger, higher and complex, a smoke control system according to domestic design guidelines might have difficulty in securing the safety from smoke in a fire. Therefore, it is necessary to adopt the performance-based design of a smoke control system that can enhance the safety and integrate the smoke control functions and design depending on the characteristics of fire and building structure in the case of fire in a large, high-rise, and complex building. This study analyzed the domestic design guidelines of a smoke control system and this paper proposes the part requiring improvement, and examines the legal system and guidelines on performance-based design of smoke control system in foreign countries.

국내의 송전선 지지물 설계는 전기설비기술기준과 한국전력공사 송전설계기준에 근거하여 적용되며, 철탑하중에 큰 비중을 갖는 풍하중기준은 1985년 기상청의 풍속 데이터를 반영하여 1987년경에 제정된 지침을 지금까지 적용하고 있다. 당시 제정된 설계기준에서는 지역별 풍속 차이에 따라 I, II, III, 지역 및 울릉도로 구분하여 차등 적용하는 설계개념으로 주변여건을 고려하지 않고 동일한 지역내에 위치하고 있는 송전지지물의 경우에는 동일한 풍하중을 적용하는 방식이다. 최근 해외 철탑설계기준과 국내 건축물 설계기준에서는 전산기술의 발달로 국부적인 지형영향을 고려하여 철탑별로 개별적인 풍하중을 산정하는 방식을 채택하고 있다. 본 논문에서는 상용 송전선로 설계가 진행되고 있는 군산-새만금 예정 경과지 가운데 지형조건을 고려한 풍속할증이 요구되는 개소에 대한 설계 풍하중 검토사례를 소개한다.

본 논문에서는 BIM TOOL 중 하나인 AUTODESK사의 Revit Softwere를 활용하여 건축물에서 필수적으로 사용하고 있는 전기 설비 중 조명설비를 대상으로 전력소비에 따라 발생하는 온실가스인 이산화탄소($CO_2$), 메탄($CH_4$), 아산화질소($N_2O$) 배출량을 추정하여 건축물 에너지절감의 필요성을 강조하고 증명하고자 한다. BIM을 적용 할 수 있는 설계, 시공, 유지보수 외에 사용자의 전력소비에 따른 배출량을 연계한 데이터를 추출하여 온실가스 감축을 위한 전력절감의 TOOL 활용과 국가 정책, 제도 및 지침에 적극 활용되기를 기대한다.

Because of ultra-high buildings or deeper underground space, recent buildings have the potential that people who have lack of physical strength collapse before arriving at the emergency exits when catastrophes occur. In case of fire, the way to escape is that first, people take the stairs of the adjacent areas and then use the elevator to the remaining distance by road to escape notice or be safe. For this reason, the skyscrapers guidelines of Seoul for information on the elevator for evacuation has been established. Nevertheless, when designing buildings to install a elevator for evacuation separately is not effective, so passenger elevators installation according to the criteria are encouraged to use as evacuation elevators. However, this does not include detailed design guidelines so far. Therefore, this study was to investigate design method to use the passenger elevator for evacuation according to the domestic law and international installation criteria, and to calculated number of lifts and refuge to use the elevator using by the ELVAC+ and PathFinder evacuation program.

With the introduction of COBie (Construction Operation Building Exchange) in BIM technology enabling an automatic transfer of design and construction information to operation and management (O&M) phase, the BIM centric O&M management system development process has been tested on the subject of architectural types of building. However, for now, there is a need to investigate the technical feasibility of COBie application to civil structures including industrial facilities. This study takes both "O&M Guideline for Public Wastewater Treatment Plant" and a real wastewater treatment plant into account for the purpose, in which the latter is intended to supplement the result of the first. The findings are three-folds: (1) COBie, as an asset modeling, is not sufficient enough to encompass commissioning data, (2) more relevant IFC development and family library build-up useful to modeling wastewater treatment plant is imperative, and (3) well-planned coordination and organization of COBie data-set in line with O&M practice will enhance the feasibility of the COBie in industrial facilities. The result could be used for a basis study for COBie application, particularly in industrial facilities.

This study outlines a successful and effective plan for repairing water-leakage cracks in concrete structures. The lack of adequate solutions for water-leakage cracks often results in unnecessarily high repair costs, and as such this remains a problem that requires constant attention. Unfortunately, despite the availability of a vast number of different materials and methods, it is often difficult to attain a perfect waterproof sealing The reason for the difficulties in the repair of water-leakage cracks can be attributed to an insufficient knowledge and understanding of the negative factors (i.e., chemical and physical (mechanical) conditions) that cause water-leakage cracks, and of the properties of the repair materials and methods. In this study, guidelines and methods for the selection of adequate materials for the repair of water-leakage cracks in concrete structures were developed for countries that do not already have general guidelines on this subject, and for local regulatory authorities elsewhere.

The startingpoint of successful buildingproduction process is the feasibility study of the project. If the feasibility study is poor which is affected in direct production processes such as designing and engineering, it incurs a great unrecoverable loss to the company. The governmentinstitutionalized the feasibility study for projects that budgets over 50billion won in an effort to ensure competitiveness of the construction industry after IMF; however, the system and effort to created systematic studies or guidance preparation for private construction development projects are lacking in great deal. Therefore, the objective of this study is to establish the analysis factors of feasibility study and evaluation standard by systematic analysis in consideration of the changes of various variables and mutual relationships using system dynamics technique for office buildings among commercial buildings.
