This research focuses on analysis of a interaction fracture of various glasses due to contact of water sprayed curtain on hot glass surface with high temperature produced from convective heat source near glass wall. A large scaled experimental test was done in order to find the range of the glass surface temperature to be able to cause the breakage of the glasses when water droplets reach on the hot surface. This paper shows the allowable temperature of the glass surface for prevention of the cooling down breakage before water curtain droplets contact the surface. Allowable Temperature if $250^{\circ}C$ for the tempered glass but general glass is very relatively low. Therefore if the water curtain spray system was adequately activated by a thermal detector installed below ceiling adjacent glass wall with water curtain nozzle system, all hot glass would not break out by cooling water droplet's contact on the hot surface due to convective heat released by adjacent fire source near the glass wall.

According to building law, there are only regulations on the fire prevention compartments that can perform the function of partial smoke compartment, but the building law management of the smoke compartment for effective smoke diffusion prevention and control is not possible. The lack of control on the smoke compartment such as leakage rate on the penetrating part, and the lack of leakage rate in the design of smoke control of fire safety law resulted in the absence of fundamental safety technology. Therefore, this study seeks to find solutions to domestic problems after reviewing relevant domestic laws and regulations.

방화댐퍼는 방화구획을 관통하는 덕트에 설치되어 화염의 전파 및 연소확대를 방지하도록 하는 방화설비로서 '건축물의 피난 방화구조 등의 기준에 관한 규칙'에서 구조 및 시험기준에 대해서 규정하고 있으나, 정해진 성능기준이 없으며 방화설비에 있어 가장 중요한 내화성능에 대해서 언급이 없는 등 개정이 필요하다. 본 연구에서는 방화댐퍼의 'KS F2840(방화댐퍼의 내화시험방법)'시험에 대해서 소개하고, 방화댐퍼의 내화시험 사례를 통해 성능 평가방법으로서의 적용 타당성을 검토하였다.

Recently the interest in disaster prevention on super tall buildings is increasing. Especially in fire, against increasing of evacuation time due to high-rise, It is being tried to minimize the fire spread in building. Fire compartments using the fire-resistant wall and door, typical method to control the fire spread in buildings, delay the fire spread to other compartments and consequently evacuation time increases. But the existing provisions adjure only 2-hour fire resistance with maximum limit regardless of the super tall buildings, so this is a obstacle for research and development of the fire resistance wall in super tall buildings. In this study, we reviewed the fire resistance ratings of the wall, and presented the development directions for the fire resistance wall in super tall buildings considering fire resistance, construction and application of the wall.

Purpose: The goal of this research is to create a numerical analytic database that may assist fire prevention managers and building officials in prioritizing items that need to be addressed in order to improve evacuation safety performance while working within a constrained budget and time frame. Method: It was carried out utilizing the CFD Tool, a quantitative evaluation approach, to assess evacuation safety. One direct staircase-type apartment houses and one corridor-type apartment were chosen to make it. Result: In the fire compartment category, Apartment A's evacuation time was around 130 percent longer than that of sprinkler facilities. Conclusion: Fire prevention managers and building officials feel that starting with a single level and implementing "dwelling unit separations" will increase evacuation safety, and that maintaining fire compartments and sprinkler systems at all times will be effective. Because of the limited characteristics of smoke propagation in corridor-type apartments compared to direct staircase-type flats, it is thought that fire extinguishing equipment should be addressed.

A sports center fire in Jecheon caused 29 deaths and 40 injuries. This study focused only on the structural factors of the building and equipment to investigate the causes of casualties based on the fire investigation results at the sports center. The structural factors of the building and equipment were a piloti-type parking lot, lack of a fire compartment between the piloti-type parking lot and lobby, lack of an installed sprinkler system, lack of an installed fire door in the main stairs on the $1^{st}$ floor, lack of an installed fire water tank on the rooftop, an installed pocket fire door in the main entrance on the $2^{nd}$ floor, poor fire compartments in an EPS space and a pipe pit and on each floor, a leak in the joint of a drain pipe, plywood installed in the hoistway of the freight elevator and interior wall, illegal remodeling of a closed rooftop structure, which cannot discharge smoke and heat, installed styrofoam insulation in the inside of the parking lot ceiling, an installed tempered glass window, which cannot be opened in the ladies bathroom on the $2^{nd}$ floor, and a finished dryvit exterior wall.

Recently, the buildings have gradually become higher, more massive and more complex with high growth of economy and varieties of the patterns of people's living. Therefore we study a performance and Improving Methods of the fire compartment as a measure to minimize the damage of the people and property from the fire. Currently, under the economic crisis situation, we do not consider about prevention of disaster safety enough; safety investment evasion, safety carelessness, and management relaxation etc. Also in the aspect of regulation system, industrial technology and plan engineering, Korean techniques of preventing fire disasters are far behind of other advanced nations. At this point, we are in need of improving about it. When considering like this situation, we need more studies on the practical improvement in order to assure fire prevention for buildings. The fire compartment prevent from magnifying the fire to the wide area by compartment into specific area. From this, it is possible to minimize fire damage and property and secure emergency exit for life safety. This fire compartment has primary function to extinguish fire easily, and the openings and penetrations are important passage which makes the smoke and fire go away from the fire area to the contiguous space. This study suggests improving methods of domestic fire compartment efficiency standard through comparative analysis of overseas advanced provision and domestic provision about base element of the building fire prevention.

설계가 잘 되어있는 문은 사람이나 물건의 출입에 큰 지장을 주지않고 분리, 차음 및 안전등의 제기능을 충분히 발휘할 것이다. 화염이나 연기의 확산을 조지시키는 일은 안전상 가장 중요한 일 중의 하나이다. 건물의 여러곳에 위치한 문의 기능, 성능의 평가방법과 기준등은 전세계에서 논의의 대상이 되고 있다. 건물의 각부분은 내화구조구획에 의해 각각 분리될 수 있으며, 각 구획을 통하는 개구부는 화재시 자기의 기능을 충분히 발휘할 수 있는 문에 의해 차단될 수 있다. 첫째, 문은 그 문이 위치한 벽체에서 화재차단의 효과를 가져야 하며, 둘째, 피난통로의 안전을 조해하는 연소부산물이 침투하는 것을 방지하여야 한다. 그러므로 모든 방화문은, 건물에서 그 위치의 정도에 따라 연기와 화재의 확산을 막는 장벽으로서의 역할이 요구된다. 본 내용은 현재 논의되고 있는 상황에 대한 영국건축연구소의 연구보고서의 요약 소개이다.
