In Korea, the relevant laws and regulations for fire safety in buildings have been revised. Since 2011, Performance-based Design has been conducted for large-scale or high-rise buildings. However, the Korea's performance-based design is still at a level where life safety evaluation using fire and evacuation simulation tools is compared with existing methods. Although related studies have been conducted continuously for the mandatory performance-based design, the fact that it is relatively unsatisfactory for design and construction of fire-fighting facilities as it mainly focuses on administrative and institutional improvement measures or computer simulation. This study collected 91 performance-based design documents that were carried out nationwide at the initial stage of implementation until 2016 to analyze the status of performance-based design of fire-fighting facilities. As a result, fire-fighting facilities, except for fire extinguish system facilities, were not properly designed for performance. Furthermore, the designers found that if corresponding facilities or higher-level equipment with upgraded performance is additionally installed, the performance-based design fared well compared to the existing the prescriptive-based design.

소방시설의 경우 지진 시 건축물의 진동 수준에 따라 2차적으로 지진하중을 받는다. 따라서 소방시설에 직접적인 피해를 입히는 수준보다 작은 지진동에 대하여 내진설계를 수행하는 것은 소방시설 설치비용이 증가하게 되어, 합리적인 수준에 대하여 내진설계를 수행할 필요가 있다. 본 연구에는 다양한 소방시설에 대한 실물 내진실험을 실시하였고, 내진설계범주에 따른 내진설계 적용필요성에 대하여 제안하였다. 실험결과 실제 지진 시 내진설계범주 A와 내진설계범주 B에 대한 건축물의 경우 현재의 소방시설로도 내구성을 가질 수 있다고 판단된다. 내진설계범주 C와 D의 경우는 건축물에 설치된 소방시설의 기능보전을 위해 내진보강 설계가 필요하다.

This project has been designed for people to experience and understand the process, importance and benefit of coal fire plants. As the biggest and first typical Korean fire plant using coal, Boryeong fire plant has had important roll for the Korean industries. Even so, people has had wrong prejudice for the fire plant in terms of environmental protection. To do these kind of rolls, this museum has been designed with theme, "Boryeong fire plant mating symbiotic relationship between nature, human and technologies." The space was zoned with five major themes: i. circulation of energy in nature, ii. electric power and eco-fire plant, iii. future energy, iv roll for future of environment, v. Korea as the leading energy industry. The design has been developed focused on spatial experiences to make 'Design Sequence' with linear circulations haying several important destinations. The interior has been finished with minimal color and materials projected by big sized movie and various LED movie system. Concept of appordance has been used to make interactive experiences between exhibits and visitors.

Considering heat insulation and beautiful sight of construction, making use of exterior panels is increasing. Recently the exterior panels now are weak very much, and so in consequence of the weakness fire spreads rapidly. Compared with internal fire, external vertical fire spread rate goes rapidly and it is extensive in spread range, therefore it is dangerous very much. Accordingly, under present condition of poor standard of exterior panels, it is required to take measure to meet the appropriate situation. In this study, by making use of FDS(Fire Dynamic Simulation) program about external vertical fire of high rise building, fire behavior is searched by computer. It is important that realizing by computer fire modeling about external vertical fire must be included certainly in procedure of fire performance design in the future. In modeling program, FDS version 5 is available, and aluminium composite panel is applied in external panels. In this study, for realizing of actual fire condition, FDS is applied by details of fire scenarios considering influence of wind.

The technique detects radiant energy form a flaming fire of fuels contained carbonaceous material can be applied to fast growing fires. This technique applied detectors are ultimately effective when early detecting fire alarm system is required or the smoke and heat detectors can not applied. In Korea Fire regulation, a flame detector should be install in case that the installation height is higher than 20[m], chemical plant, hangar refinery. Therefore it is really necessary that a flame detector has to be developed as soon as possible. With foundation technique of flame detector, ideal sensing element and stable circuit design, a trial UV flame detector is manufactured. The stable and reliable technique of flame detector is established through the repeateed perfomance test and modification. An early detecting fire alarm device is developed through the modification, supplement of the structure and circuit. Results of the R & D for the manufacture of an excellent flame detecting device is carried out with the establishment of technique for the mass production and the qualified manufacturing process.

This is the study to investigate the Algorithm of BRI 2002 which is high level estimation program of smoke movement and phenomenon for performance based of design named 'ROOT C', made by Japan. The aim of this study is that an analytical model is a fire in a three story building. The outline of the building consists of three usual rooms, one on each floor, and an atrium connecting with these rooms.

Recently as the testing of fire detector used the testing device for fire detector, there are something the matter in the perception function loss of fire detector, structure and form of the testing device for fire detector. The problem at oxidation of emitting smoke ashes hazardous article part and so on that checking person absorbs be. In this paper the problem or the conventional the examination equipment of fire detectors is analysed and researched. To solve these problems after the theoretical study and design and paint drawing of equipment the prototype of composite examination equipment of fire detectors was made. After compared with the conventional, part that improve of composite examination equipment of fire detectors are verified through the examination. In the future it will be useful the operation state and correct operation time of the fire detectors are measured after the research about the quality of the material and transparency of bellows cover is done.

The current status of Performance-Based Design (PBD) implemented in 4 wide areas (Seoul, Gyeonggi, Incheon and Busan) over the past 5 years was reviewed with regard to the number of PBD implementation and target buildings. Then, detailed status related to fire scenarios, input information for fire simulation, and grid size were analyzed with the pre-review for the PBD. As a result, the domestic PBD was mainly applied to the mixed occupancy. In the fire simulations performed on the identical fire scenario and fire space, the maximum heat release rate (HRR) varied significantly depending on the PBD designer. Various combustibles were also considered for the identical fire source, and their combustion properties also showed considerable uncertainty. In addition, the applicability of accurate input information for predictive models of heat and smoke detectors was examined. Finally, the average grid size for the fire simulation using Fire Dynamics Simulator (FDS) was analyzed, and the improvement of PBD to minimize designer dependency was proposed.
