  • Type R fire alarm is required intelligent buildings and height buildings which was based on automatic system. But in Korea, maintenance of fire alarm system is very poor. In this study, we developed assessment model for the type R fire alarm system which was assessed by using 96 checklist items. The assessment model was tested through the actual 4 buildings with type R fire alarm system. It is shown that present model can be applied for the assessment of all buildings through the examination of the suitability of assessment model by actual assessment. Also, it was made easily fire manager to carry out checklist for type R fire alarm system in buildings.

  • The field of structural fire engineering has evolved within the construction industry, driven largely by the acceptance of performance-based or goal-based design. This evolution has brought two disciplines very close together - that of structural engineering and fire engineering. This paper presents an overview of structural systems that are frequently adopted in tall building design; typical beams and columns, concrete filled steel tube columns and long span beams with web openings. It is shown that these structural members require a structural analysis in relation to their temperature evolution and failure modes to determine adequate thermal protection for a given fire resistance period. When this is accounted for, a more explicit understanding of the behaviour of the structure and significant cost savings can be achieved. This paper demonstrates the importance of structural fire assessments in the context of tall building design. It is shown that structural engineers are more than capable of assessing structural capacity in the event of fire using published methodologies. Rather than assumed performance, this approach can result in a safe and quantified design in the event of a fire.

  • Current fire safety in the construction sites has developed piecemeal over a considerable period of time. However, the law and regulation of fire safety is insufficient to protect fro in the construction sites. The frequency of fire in the construction sites is very rare but it brings longterm deterioration durability of building structure and large scale industrial calamity. There are many process of works and each work deals with many kind of flammable material, so it is very difficult to find a proper safety fire prevention. This study executed the questionnaire and fire experiment of the welding work to provide effective fire prevention counterplan.

  • In this study, a series of fire tests was carried out to evaluate fire-induced damage to structural members in tunnels. From the tests, the loss amount of concrete materials by the RWS fire scenario was slightly bigger than by the RABT fire scenario. Especially under the RWS fire scenario where the maximum temperature is over 1,200, the loss of concrete materials was mainly induced by melting. Generally, the loss of materials in reinforced concrete was slightly smaller than that in unreinforced concrete. Depending upon an applied fire scenario, fire-induced damage to shotcrete was quite different. From the real-time investigation of a specimen surface by a digital camcorder, it was proved that the material loss under the RABT fire scenario was mainly induced by spalling. However, it was also revealed that although fire-induced damage in the initial heating stage under the RWS was so close to that under the RABT, the material loss under the RWS at the later stage after 50 minutes elapsed since fire initiation was induced not by spalling but by melting.

  • 재실자가 부속실로 피난할 때 부속실 송풍기가 작동하기 전 단계에서는 방화문 개방과 더불어 실내화재로 인한 풍속이 발생하고 화재로 인해 발생된 연소생성물이 부속실을 오염시켜 피난에 어려움을 가져올 수 있다. 스프링클러가 화재풍속에 미치는 영향을 확인하기 위하여 수치해석을 진행하였고 스프링클러의 유무와 분사되는 액적크기에 따른 화재풍속을 비교하였다. 해석은 실제 공동주택의 형상과 치수를 반영해서 진행하였다. 수치해석 결과, 스프링클러가 설치되었을 때 화재풍속이 감소된 것을 확인할 수 있었다. 또한, 액적이 작을수록 화재풍속이 작은 것을 확인할 수 있었다.

  • Followings are the analysis of 578 fire accidents occurred at Specific Building In 1995. Fire frequency had been slightly decresed since 1992. In regional, fire accidents in Seoul and Ulsan were higher than the average. Occupational fire frequency order was apartment, factory, buildings over six stories and market place. In addition, the order of life loss was buildings over six stories, apartment and factory. And property loss totaled six times higher than that of Fire Department. Among the causes of fire, electrical fire formed 44.8%, from which we can assume that there were some problems in the investigation of fire causes.

  • Pool fire는 본격적인 화재연구의 시작과 더불어 그 구조 및 특성에 대한 연구가 지속적으로 수행되어 왔다. Pool fire는 복잡하고 취급하기 어려운 화재의 제문제들을 비교적 간단하게 다룰수 있게 하면서도 현실과 괴리되지 않는 형태를 가지는 가장 기본적인 형태의 화재로, 학문적 측면뿐 아니라 응용측면에서도 매우 유용한 결과 및 단서를 제공하여 왔다. 따라서, 본고에서는 pool fire의 특성을 화염기저(flame base)부근과 플륨(plume)부근으로 나누어 그 동안 발표되었던 연구결과를 정리하고, 화재 시뮬레이션을 위한 zone 모델기법의 가장 중요한 부분의 하나인 연기량 산정과 플륨해석이 어떤 형태로 연결되는 지를 설명하고자 한다.

  • The fire protection system of Nuclear Power Plants(NPPs) is an integrated system that is applied multi-field technology. So, it needs synthetic design and analysis, that is, the plan of fire protection, fire compartment, fire detection, fire suppression, and success of safety shut down, etc. In case of a fire in NPPs, secure the safety of reactor and minimize the radioactivity contamination. For this purpose, perform the fire risk analysis and make up the deducted problem through the improvement of design or the change of operation process.

  • Fire safety engineering is a critical specialization to include in the design of a tall building yet is often excluded from the Building Information Model (BIM) and integrated design process. The design of fire safety systems is interdependent with building/structural geometry, HVAC, mechanical, and electrical systems. A BIM is a 3D visual representation that stores data on these kinds of systems. The compatibility between BIM and fire safety design seems obvious yet has received a dearth of attention in structural (fire) engineering literature. The authors herein have reviewed over 40 recent papers on utilizing BIM for fire safety engineering, focusing on contemporary literature to obtain a more up-to-date review of the state-of-the-art. The resulting trends, technologies, research gaps, and methodologies are presented in this paper. Adoption of BIM in fire safety engineering is slow and behind other disciplines which may be improved if research involved more industry partners. For BIM technology to reach its potential, industry manufacturers need to provide high LOD fire BIM objects, fire engineers and researchers need to collaborate on future advancements, and building owners/management need to be educated on how to use the benefits provided.
