  • When the fire door is recently installed in the field, there are frequent cases where the fire door is manufactured with fire door having low quality or different structure compared to the performance that the fire door producer has confirmed in the performance test or the construction specification. Accordingly, on-site quality management and maintenance guideline for fire doors were presented. In this paper, we tried to explain the requirements for the construction of fire doors during the on-site quality management and maintenance guideline for fire doors presented in the study.

  • The purpose of this study is to find out the failure conditions of fire doors in the process of use and prepare maintenance measures against them and find out the failure conditions and failure rates of fire doors according to the period of use of buildings. According to a survey of the failure rate and failure factor of fire doors, the failure rate of fire doors under 5 years was 3.7%, 13.4% of fire doors under 5 years and 10 years, and 14.8% of fire doors under 15 years and 27.6% of fire doors over 20 years. In particular, 15 years later, the failure rate of fire doors exceeded 20%. The main defects were found to be natural aging, holes, opening and closing failures, gaps, and failure and wear of accessories such as gaskets and door closers.

  • There are continuous cases of fire expansion due to fire door problems around the world, including the 2010 Shanghai Apartment Fire, the 2017 Grenfell Tower Fire in England, and the 2020 Ul-san Residential and Commercial Complex Fire. In order to prevent such fire damage, the country has strengthened the performance standards of fire doors, and recently, efforts have been made to ensure the best performance of fire doors by introducing a quality recognition system. Securing the performance of fire doors is a very important aspect. However, there is a concern that old fire doors may not function normally in the event of fire due to natural deterioration, corrosion, and damage during the use process, but countermeasures are insufficient. Therefore, from a management perspective, it is very important to maintain fire doors and secure an appropriate replacement time. Therefore, the purpose of this study is to determine whether the fire door has durability to prevent fire spread in the process of use through operation probability analysis and expert surveys, and to propose an appropriate useful life of the fire door.

  • Seoul Metro has been constructing the screen doors on the platforms to provide safe and comfort environments. The screen doors of each station are configured so that they can be operated in automatic mode in connection with ATC/ATO through the integrated control panel in the station control room and in manual mode through the control panel of the station control room and crew control panel. These systems have been implemented with different data communication protocols between systems, HMI configuration, and so on due to ordering processes, implementation time and diverse suppliers, and manufactured to be operated within single station. Seoul Metro has been planning to implement the integrated control system to secure seamless train operation and safety and to have a fast response system against emergency situations such as PSD failure and fire, by implementing the system that is able to collectively manage, monitor and control the operation status and equipment conditions of PSD on to the integrated control center. This paper has studied a scheme to reduce the budget for the future facility constructions by standardizing the data format for data communication with the integrated station control panel and using the open standard protocols, in order to secure consistency of operation, system expansion and maintenance with unified and standardized control items.

  • 도시 인구의 과밀화로 고층 건물에 대한 폭발적인 수요와 공급이 발생하였다. 고층 빌딩은 각 도시의 구심점으로 도시 이미지를 제고하는데 기여하고 있으나 연돌효과로 인해 승강기 문의 오작동, 외벽의 문과 창문 개폐의 어려움, 상층부로 확산하는 연기와 악취, 소음, 에너지 손실, 화재 및 오염물질의 급속한 확산 등 예기치 못한 다양한 문제를 야기하고 있다. 본 연구에서는 초고층 건축물을 수직조닝별로 구분하여 연돌효과의 원인과 해결방안을 분석하고 설계와 시공 방안으로 도출하였다. 외기를 차단하는 초기 계획과 정밀한 시공을 통한 기밀성 확보를 통해 저층부에서 유입되는 기류를 능동적으로 차단하여 건물의 내·외부 기밀성을 확보하는 방안을 모색하였다. 설비적 해결대책은 연돌효과로 인한 특정 현상을 줄이기 위한 대책이 될 수 있으나 이에 따른 2차 피해의 가능성이 높기 때문에 최소한으로 적용해야 한다. 따라서 본 연구는 연돌효과의 원인과 대책방안을 수직 조닝별로 설계적, 시공적 대책을 제시함으로써 체계적인 연돌효과 관리의 필요성을 역설하였다. 또한 본 연구가 설계 및 시공뿐만 아니라 건물 유지관리에도 도움이 되기를 기대한다.
