This study analyzes the issue of the supply of force of fire in the high-rise buildings, and proposes an efficient method to do so. The results are as follows. First, in terms of Detect fire, it is necessary to shorten force of fire supply time by diversifying fire alarms such as alarms, vibrations, and voices from outside, clarification of fire occurrence points, and marking of fire. Second, with regard to communication signals, strengthening the installation target of wireless communication auxiliary facilities, supplementing the installation of repeaters, and constructing a multicommunications network were proposed. Third, in terms of Decide action, it is necessary to supply firefighter and firefighting equipment with the method of crossing of a river in adjacent buildings. Fourth, in terms of Respond to site, helicopters and emergency elevators are used to assist in the supply of firefighting equipment using drones. Easy-to-break glass windows and identification marks are required in every floor. Finally, in terms of applying fire suppressants, water can be supplied by means of a helicopter adjacent to the structure.

This study was accomplished by analyzing the change of land cover pattern in high-rise buildings in Korea. For this study, we selected 15 locations of high-rise buildings. The ratio of average building coverage and paved area was 79.7%, and both green and water area were low, relatively. The biotope area factor of the site showed low percentage by 15.90% due to the underground space development. As a result of correlation analysis between the time of construction and land-cover type, building coverage has been decreased according to the stream of time. However, biotope area factor has been increased And, the paved area has m correlation. It was identified that reducing paved area is effective to enhance the ecological functions of a high-rise building outdoor.

This study analyzes the current usage of SD500 high-strength re-bar in domestic construction sites. Also, an evaluation method was developed to measure economic efficiency of lap splice and coupler splice, which are most commonly used in connection SD500. The evaluation method was applied to construction sites in Seoul in December 2006, and the result revealed that coupler splice is relatively superior in terms of cost efficiency when the re-bar diameter is bigger and the concrete strength is lower.

최근 초고층 건축물에 대한 수요가 증가하고 있고, 더욱이 건설기술의 발전에 힘입어 초고층 복합빌딩의 계획과 건설이 더욱 증가하고 있는 추세이다. 이러한 초고층 복합빌딩에서 화재 등과 같은 재난이 발생할 경우 거주자의 대피 및 소방공무원의 화재진압 활동이 어려워 국가적 재난으로 확대될 위험이 있다. 그렇기 때문에 초고층 복합빌딩에서 발생하는 사고를 예방하거나 발생하는 사고의 피해를 최소화하는 등 재난관리를 통합적으로 하기 위한 방재정보센터의 운영이 무엇보다 중요시되고 있는 실정이다. 본 연구에서는 초고층 복합빌딩의 개념과 문제점에 분석하고, 방재정보센터의 특성 및 향후 방안을 고찰하였다.

Domestic and foreign high-rise buildings are expected to continue to increase in the future. In addition, recently, residents and landlords are demanding maintenance necessary to secure the performance of sustainable buildings, so an effective management plan is needed. Therefore, this study aims to develop customized technologies that can be effectively applied to building structures by comprehensively analyzing existing technology-based research cases. As a result, it is expected that this will serve as a stepping stone to present a s+ample of future technology development along with a reduction in labor dependency on maintenance and quality improvement.

Recently, Incidence of natural disasters are growing gradually. The need for a monitoring system for maintaining the structural integrity of the high-rise buildings against extreme weather events such as typhoons, earthquakes is increasing gradually. One of the most important features in the tall building is to guarantee structural safety during the structure's life time. Structural monitoring technologies might be needed to manage structural safety and to protect human life.

최근 건축물은 삶의 터전, 생활의 터전에서 벗어나 미를 상징하는 또 하나의 예술품이다. 고급스럽고 아름다움을 지향하는 요즘 건축물에는 유리가 주 소재로 이용되고 있다. 심지어 초고층 대형 건축물에 있어서도 대형 유리는그 고풍스러움을 더해준다. 국내 최고의 유리 가공업체인 비봉이앤지는 8미터가 넘는 대형 유리까지 특수 제작함에있어 안전을 등한시하지 않는다. 오늘 대한산업안전협회 수원지회 박창옥 계장과 함께 현장을 찾았다.

In the disaster prevention design, it is important point to secure escape way at event of fire which makes people away from the fire more quickly and safely. Development of construction techniques leads to build many skyscrapers, and skyscrapers contains various dangers and increase levels of disaster. At basic design stage for skyscrapers, evacuation scenario is considered that occupants are escape using escape stairs and emergency elevators simultaneously at fire, but there is no evacuation program to simulate using escape stairs and emergency elevators at the same time. In this study, evacuation simulation is performed using method of VR which is based on Virtools of 3DVIA Co., and Simulex of IES Co. for safety and effectiveness where occupants are escape using escape stairs and emergency elevators simultaneously at the fire.

본 연구에서는 초고층 건축물에서 피난을 할 때 피난자에게 작용하는 신체 조건과 수직적 이동방향에 따른 피난시간을 분석하였다. 초고층 건축물에서의 피난은 특성상 많은 계단을 통해 이동해야 하므로 피난자는 심리적 행동보다 주로 신체적 능력에 의존하는데, 이 때 피난자의 피로도는 계단수가 올라갈수록 급격히 상승하게 된다. 즉, 총 피난시간은 단순히 피난자의 평지 보행속도에 비례하여 증감할 뿐만 아니라 체력 등의 다른 신체적 영향 또한 받게 된다. 따라서 본 연구에서는 피난자의 신체조건을 고려한 피난예상시간을 산정하기 위해 필요한 조건들을 연구하고자 실물 실험에서의 상 하향의 보행방향과 참가자들의 신체조건에 따른 피난시간을 통계적으로 분석하였다.
