Heat release characteristics of live fire load are an important parameter for performance oriented fire safety design of a building. While investigations have been carried out on the fire load and its burning behavior in office, residential and commercial buildings and so on, little effort has been paid for the rational treatment of fire load in bookstore. In this report, burning behavior of typical combustible objects in bookstore are studied by measuring heat release rates of bookshelf with book.

As building becomes larger, taller and more complex due to industrialization and urbanization, it tends to be vulnerable to fire and establishment of effective measures for fire safety is demanded. Especially the fact that the smoke hinders evacuation and fire-fighting activities as well as becomes the major cause of life casualty emphasizes the importance of smoke control system. To design and operate the smoke control system success folly, it is necessary to analyze and predict precisely the thermoflow induced by fire in building. The unsteady three-dimensional analysis of thermoflow induced by fire with diverse variables such as building structure, fire conditions and smoke control facilities can be effectively carried out with numerical method In this study, using the FDS(Fire Dynamics Simulation) program that spreads widely as the analysis tool for thermoflow of fire, the analysis of thermoflow in partition of building induced by fire and comparison with the experimental results for assessment of numerical analysis are presented.

가스계 소화약제시스템의 인명안전 또는 기타 안전관련으로 CO2 시스템과 청정약제시스템을 중심으로 기술해보았습니다. 인명에 대한 위험을 최소화하면서 CO2 소화시스템의 혜택을 얻기 위해서는 설계, 시공, 유지관리면에서의 인명안전에 대해 상당한 관심을 기울여야한다. 청정 소화약제를 통상의 거주구역에 사용할 경우의 주요요소는 독성문제이다. 할로겐화탄소약제 테스트에서의 주요 관점은 급성효과, 즉 단기간 노출의 경우이다. 주요급성효과에는 마취성과 심장감작성이 있다. 불활성가스약제의 경우 주요 신체적 영향으로는 산소농도의 저하문제를 들 수 있다.

Two new formulae for the design of beam-columns at room temperature have been proposed into Eurocode 3, prEN 1993-1-1 (2002), and are the result of great efforts made by two working groups that followed different approaches, a French-Belgian team and an Austrian-German one. Under fire conditions the prEN 1993-1-2 (structural fire design) presents formulae, for the design of beam-columns based on the prENV 1993-1-1 (1992). In order to study the possibility of having, in part 1-1 and part 1-2 of the Eurocode 3, the same approach, a numerical research was made using the finite element program SAFIR, developed at the University of Liege for the study of structures subjected to fire.

The present study investigates the effect of balcony on external smoke movement of high rise building through the fire tests of the 1/10 reduced model scale using Froude scaling. A hexane pool fire is used to examine the smoke movement for various opening sizes of balcony and temperature distributions are measured by T-type thermocouples. Also, hydrogen bubble technique is applied to visualize the smoke movement near the balcony. Measured temperatures of the closed balcony is 2.5 times higher than those of the open balcony because the external smoke in case of the closed balcony rise along the vertical wall. The maximum vertical temperature of partially closed balcony is similar with fully closed balcony and mean temperature inside of balcony increases as opening size of balcony decreases. The experimental results show that the balcony space plays an important roles in preventing fire propagation and cooling of smoke layer. In order to ensure the fire safety in high rise building design, a series of systematic researches are required to examine the various type of balconies.

본 연구에서는 수계 시스템 중 스프링클러 헤드 파이프라인에 대한 내진설계를 수행하였다. 내진해석에 필요한 내진설계용 스펙트럼에 대응하는 인공지진 진동파형을 작성하고, 작성된 인공지진 진동에 대한 동적 응답스펙트럼을 해석하였다. 내진설계를 위한 공학적 기반을 구축하였으며, 수계 및 가스계 파이프 시스템의 내진설계 기법을 제시하였다. 또한 본 연구의 결과로부터 수계 시스템의 파이프라인뿐만 아니라 소방시스템의 내진설계 및 성능평가에 응용할 수 있는 기틀을 마련하였다. 향후 진도규모 및 지반종류에 따른 추가적인 연구가 수행된다면 소방시스템의 신뢰성 향상과 안전성 제고, 성능위주설계가 이루어질 수 있을 것으로 본다.

위험물저장 탱크기초의 결함으로 인한 인화성물질의 유출사고는 산업단지의 대형화재를 야기시킬 수 있으므로 탱크기초의 설계 및 시공단계에서 세심한 주의를 기울여야 한다. 본 연구에서는 위험물저장탱크 기초의 설계 및 시공 가이드라인을 제시하기 위하여, 대표적인 탱크기초 유형을 분류하고 각 유형에 따른 대표단면을 모델링한 수치해석(3D FEM)을 수행하였으며, 수치해석 결과로 나타난 탱크기초의 응력 및 침하분포를 비교 평가하여 각 기초 유형별로 위험물저장탱크 설계 및 시공단계에서 유의 하여야할 사항을 검토하였다.

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.

In this study, the independent variables are the floor plan configulation. The dependent variables are the occupant's egress behavior, especially spatial movement pattern, and life - safety performance of building. Fire events were simulated on single story of office building. Simulation run for allowable secaping thime(180 seconds) arbitrarily selected, and involved 48 occupants. The major findings Pre as follows. 1) Computer simulation model suggested in this study can be used as the Preoccupancy evaluation method of the life-safety performance for architectural design based on prediction of occupants' egress behavior in the levels of validity and sensitivity, 2) Sucess or failure in occupants' escape is determined by decreasing walking speed caused by jamming at exits or over crowded corridor, and increasing route length caused by running about in confusion at each subdivision and corridor. 3) In floor plan configuration which safe areas located at the extreme ends of the corridor, cellular floor planning have to be avoided preventing jamming and running about in confusion at overcrowded corridor.

This study is to research on the condition of safe environment of kindergartens. This study is to supplement the preceding study which was based only on survey to show the result and analyze the condition and problems of the safety of kindergartens to suggest the basic database of indoor environment that cause accident. First as a theoretical study, we analyze the preceding studies according to the related regulations. And we made checklist based on this and visited and investigated two kindergartens where applied for the case study As the result, we could understand factors that can cause accidents from classroom, corridor, door, stairs, balustrade, toilet, kitchen, front door, and fire exit/shelter. Especially, in case of fire exit/shelter, the whole renewal of kindergarten was necessary which is difficult. But, though it can not be advanced right away, they should try to have facility expansion and repair works gradually. And for more study on this, active cooperation from kindergartens are in need.
