  • In general, fire resistance is determined through the building' uses and stories. But recently a fire engineering design that is done by the calculation of design fires from the fire cell and an evaluation of stabilities for structural behavior at fire condition have applied to almost of countries as a major alternative against a prescriptive fire design. To adopt and utilize the fire engineering design into Korea, at first, we evaluated structural stability of 21st stories steel residential building at fire condition through fire engineering design and secondly the fire protection cost was analyzed with fire engineering design method and the prescriptive one, respectively. No fire protection materials for satisfaction of building law at structural members such as columns and beams were needed and about 90 % of fire protection cost was saved.

  • Fire was and remains a great threat to historic buildings of wood. This threat is omnipresent and often results to irreparable property losses especially cultural heritages. Fire of historic buildings continues to increase every year. The purpose of this study is to preserve a life safety, historical heritage and architectural & cultural values by pursuing for fire safety in the historical buildings. This study shall employ two research methods: a literature review and field survey methods. The literature review shall focus on the observations of characteristics noted in fire codes. The field survey shall cover a heat analysis and fire protection equipment. A method is proposed to investigate fire codes related historical building, reported fire history Fire Codes and Regulations for modern buildings are not always applicable on the historic buildings. Old buildings, and some new buildings with architectural, historical or cultural importance may have values which cannot be measured on a monetary scale. Their protection against the damage caused by fire is considered to be one of the basic moral duties of society. It is strongly recommended, therefore, legislation for fire safety in historical buildings must be extended to a complementary relationship with 'active' fire protection measures, to provide safety in real historical building in real fire situations. The development and application of performance based Codes and the Fire Safety Engineering approach seems to be a rather reasonable and effective way to deal with this historical buildings.

  • As buildings in South Korea become more skyscrapers, the risk of fire is also emerging. Thus, regulations, regulations, and guidelines are being improved to prevent the spread of smoke in the event of a fire in high-rise buildings, but research on smoke flow and pressure distribution in vertical spaces is insufficient. Therefore, in this study, the temperature of each floor in the vertical space according to the size of the fire is measured through the miniature model experiment, and the pressure difference is calculated to establish the basic data for the improvement of the performance of domestic air supply facilities in the future. Thus, a scale model of one-sixth the size of the actual building was produced to measure the temperature, and the pressure difference was derived by substituting the value for the expression. The pressure difference varies depending on the size of the cause of the fire, and it is believed that the differential pressure and conditions of the building should be taken into account before calculating the supply volume for the analysis of the pressure difference according to the size of the cause of the fire in the event of fire.

  • Recently, construction projects are gradually becoming high-rise and large-scale, and furthermore, the use of new buildings is emerging through the deepening of the underground. In this situation, a lot of fire damage has occurred in recent years, mainly in buildings and tunnel structures. In particular, damages caused by fires during large-scale construction projects such as freezing warehouse accidents are increasing. In this situation, in Korea, it is still trying to secure safety from human fire through the administrative system divided into the building law and the fire law, but it is being developed in a negative direction rather than a positive direction. The fire risk is getting bigger even when the road is not maintained. In this current situation, it is considered that the development of a Korean integrated life safety code centering on the consciousness base of Koreans will be necessary, and in particular, the ease of revision will also be needed by promoting the integrated safety code rather than current laws and regulations. This is a summary of the future tasks.

  • In Korea, the risk of fire in buildings is increasing. Therefore, efforts are needed to reduce casualties and property damage. Accordingly, it is important to limit the flashover so that the fire inside the building does not expand to the outside. Flashover refers to the generation of upward airflow after the fire in the compartment, and when combustible gas accumulates in the upper part of the fire chamber and reaches about 500℃, explosive expansion combustion occurs inside the compartment. This can suppress flashover due to limitations on building interior materials. To this end, internal limitations are being implemented at home and abroad through standards related to internal materials. In this paper, we intend to secure basic data on domestic fire safety design by comparing domestic and foreign standards and reviewing the Japanese housing interior design manual.

  • Regulation of Escape and fire-prevention of Building of South Korea were enacted as a part of building codes in 1962. Since it was enacted, the law has gone through many changes. In this study, evaluated the fire safety of the law about the case of a hotel that the fire risk are expected to be higher whenever it was changed. As a result, the current law has gotten better in tire safety since it was enacted. However, especially it could be confirmed that the evacuation safety is insufficient in the lower level of hotel building. In the case of accommodation, because the occupants become aware of fire lately, they have not enough time to escape. Therefore, this study suggests that it is needed to come up with an effective counterplan about the interior finish materials, fire door and fire compartments that the smoke layer descending time is longer.

  • In case of fire in a high-rise building fire can be easily spread along the building external walls dramatically if the flame comes out through broken windows. There are a few effective methods to prevent the fire spread at the moment. One is using a fire resistance window, and the other is using a window sprinkler that discharges water to resist flame in case of fire. In this study a window sprinkler which is installed on top of windows and prevents fire by discharging water when its heat-responsive element opens was tested using a large scale furnace in accordance with the standard temperature-time graph. Test result showed that one window sprinkler was able to protect a 2,400 mm wide window from fire for 2 hours and the window backside's temperature locally increased up to $126^{\circ}C$ but kept stable around $100^{\circ}C$ for the test duration.

  • Fire characteristics of a typical apartment building in Korea was studied through full scale experiment and zone model simulation. The fire was ignited at the living room and allowed to spread to other parts of a single unit in a five storied apartment building. Various data including temperatures, species concentrations, and images were collected in the experiment. A zone model(CFAST) was used to analyze the same apartment building that represents the average households in Korea. The results were compared with a full scale experiments. While CFAST allows one compartment involved with fire, the experiment allowed the fire to spread to other compartments. Therefore, the comparison between experimental data and Zone-Model data is valid until the living-room fire spread to other parts of the apartment. Flashover occurred at approximately 380 seconds in a fire experiment, and at approximately 420 seconds in Zone-Model. Based on all of data between experimental data and Zone-Model data, it is concluded that the safe escape time is about 250 seconds.
