It is noted that the disaster such as fire, explosion, collapse has been rapidly increased caused by strength deterioration of steel structures at petrochemical plant during fire. In this regard, it is stressed out that the legal requirement for fire proofing for steel structures at petrochemical plant should be carefully reviewed since the current legal requirement such as Industrial Safety & Health Law, Architectural Law has a conflict and different way of approach. In addition, it is our point of view that the present law should be revised to consolidate into single law including engineering design criteria to reflect unreasonable legal requirement. It is further our point of view that the performance certificate for fire proofing like UL-1709, basis of maintenance should be appropriately and reasonably provided in line with global practice.

Recently, railroad long tunnels are increasing and growing longer due to topological feathers like a lot of mountain in Korea. But fire disaster of a long tunnel cause many people to injury and death. For that reason, at the early design stage of a long tunnel, risk assessment and mitigation measure of risk for satisfying tunnel safety are required. According to the railroad facility safety standard (Korean MLTM Announcement No. 2006-395), risk assessment for railroad-tunnel fire should be performed when design stage. Therefore, various methods of risk assessment for tunnel fire have been studied and applied. In the paper, QRA(Quantitative Risk Analysis) for fire risk assessment by using CFD code is presented and the usefulness of CFD is discussed.

In the Building Act, performance-based fire safety design is being promoted for institutionalization. The behavior of the structure against fire conditions can be predicted by using the advanced numerical analysis method based on the FEM (Finite Element Method) to predict the entire structural behavior including the behavior of the structure, but there is a limit to expressing the fire properties of the space and predicting the fire properties It is difficult to determine the variables to be transmitted to the FEM (Finite Element Method) model from the fire simulation results using FDS (Fire Dynamics Simulator). Accordingly, the purpose of this study is to introduce the code user's manual for FDS and FEM unidirectional coupling analysis.

Firesafety design engineerings have been mainly derived from complicated rearrangement of descriptive specifications in codes or regulations through a great number of lessons from fire disasters. In this paper, the author refers to some recent developments in the field of building fire protection. At first, the author expresses his viewpoints concerning performance-based design codes, which have been popular throughout the world as a symbol of freedom from restricted usage of building materials and components prescrived in regulation or bylaws, in spite of some conflicts between objects-oriented design method and industrial mass production. Secondly, the author introduces several innovative fire protection methods adopted for large or void spaces in building complex. Finally, the author forcasts a next development of firesafety science and technology, aimed at securing personal safety in hyperscale urban areas.

This research studies in the field of domestic fires are an issue in many scientific fire research as a research method to validate the domestic environment and ISO-9705 housing on the basis of experiments in virtual space by making a single fire compartment space for conducting experiments and Appearance of a fire occurring within each flammable Heat Release Rate analysis was carried out mainly. Placed within the space of one flammable HRR calculated as the sum of the number of single-room fire experiments conducted and the results compared with the value in comparing the conduct of fire locations and fire load within the building area of the future, the HRR value represents the change in domestic a consideration of the safety of the building is to propose matters.

성능위주의 설계가 법제화 되면서 화재 및 피난에 대한 연구가 활발히 진행 중이다. 성능위주설계는 인명의 안전성을 증대 시키는 방향으로 발전되어야 한다. 또한, 성능위주의 설계는 소방분야뿐만 아니라 건축법령에서 정하고 있는 피난에 관한 규정을 포함하여 검토되어야 한다. 본 논문은 성능위주의 설계 시 참고가 될 자료로 제시하기위해 다중이용시설인 광주광역시의 OO나이트클럽을 하나의 모델로 삼아 피난시간을 예측하였다. 이를 위해 우리나라와 외국의 피난에 관련된 규정과 연구논문들을 검토하고, 현장을 방문하여 자료를 수집하였다. 그리고 수집된 자료들을 피난프로그램인 Simulex의 입력 자료로 사용하여 피난시간을 측정하였다. 이 연구의 검토과정 및 결과에서 몇 가지 문제시되는 사항을 발견할 수 있었다.

해마다 반복적으로 인적 물적 피해를 유발하여 사회 안전에 큰 영향을 미치는 산업재해, 교통사고, 화재, 범죄 등의 항목을 4대 사회안전지표로 선정하여 2003년 이후 시계열에 따른 변화 추이를 분석하였다. 2003년을 기준으로 산업재해가 27.8% 감소하여 가장 두드러지게 개선된 것으로 확인되었으며, 교통사고와 범죄자표는 12% 정도 저감된 것으로 나타났다. 그러나 화재의 경우 2006년 이후 국가화재분류체계가 바뀌면서 경미한 생활 화재도 발생건수에 포함되도록 변경되어 기준년도 대비 40% 화재안전지수가 증가한 것으로 나타났다.

Post-earthquake fire (PEF) can lead to a rapid collapse of buildings that have been partially damaged as a result of a prior earthquake. Almost all standards and codes for the design of structures against earthquake ignore the risk of PEF, and thus buildings designed using those codes could be too weak when subjected to a fire after an earthquake. An investigation based on sequential analysis inspired by FEMA356 is performed here on the immediate occupancy (IO), life safety (LS) and collapse prevention (CP) performance levels of two portal frames, after they are pushed to arrive at a certain level of displacement corresponding to the mentioned performance level. This investigation is followed by a fire analysis of the damaged frames, examining the time taken for the damaged frames to collapse. As a point of reference, a fire analysis is also performed for undamaged frames and before the occurrence of earthquake. The results indicate that while there is minor difference between the fire resistances of the fire-alone situation and the frames pushed to the IO level of performance, a notable difference is observed between the fire-alone analysis and the frames pushed to arrive at LS and CP levels of performance and exposed to PEF. The results also show that exposing only the beams to fire results in a higher decline of the fire resistance, compared to exposing only the columns to fire. Furthermore, the results show that the frames pushed to arrive at LS and CP levels of performance collapse in a global collapse mode laterally, whereas at the IO level of performance and fire-alone situation, the collapse mechanism is mostly local through the collapse of beams. Whilst the investigation is conducted for a certain class of portal frames, the results confirm the need for the incorporation of PEF into the process of analysis and design, and provide some quantitative measures on the level of associated effects.

본 논문은 관리자 중심의 지하철사고 대응 매뉴얼을 사용자 중심의 지하철안전 가이드로 바꾸어 시민 스스로 사고를 예방할 수 있는 안전의식의 필요성을 알리는 연구이다. 최근 국제 사회를 보면, 공공장소의 테러와 대형 재난 재해가 급증하고 있다. 특히 지하철 화재사고의 경우 대처방법에 따라 대형 인명피해로 이어질 수 있으므로 예방과 사고 시 대처방법이 중요하다. 그러나 지하철의 화재 안전 가이드는 현재 홈페이지에 가장 자세히 안내되어 있지만, 역사 내 홍보물은 역마다 각기 다른 위치에서 통일성 없는 내용으로 홍보하고 있다. 사용자 중심의 지하철 화재 안전 가이드는 첫째, 공공디자인의 이해를 바탕으로 남녀노소 누구나 알기 쉬운 유니버설디자인의 법칙이 적용 되어야 하며 둘째, 기관마다 다른 방식의 홍보물을 통한 일방적인 홍보가 아닌 일관성 있는 디자인과 커뮤니케이션이 필요하고, 마지막으로 일상에서 사용성과 접근성을 높여 시민 스스로 안전의식을 높이고 더 나아가 사고예방 훈련 및 캠페인의 참여로 확장되어야 한다.

It has been recognized that the escape facility planning is very important for effective evacuation of accupants on fire event. The ultimate goal of the escape facility planning is to evacuate occupants rapidly from building fires to the safe areas. In fire event, occupants usually gather, utilize and finally act upon information about state transient of building fire system, which is consisted of components of fire, building and accupant during the ralatively short period of the fire event. That is, occupants' egress behavior is largely dependent upon building fire system. Therefore, comprehensive study for the relationship between building fire system and occupants' egress behavior is needed. This study aims to suggest the pre -occupancy evaluation method of the life safety performance for the architectural design based on prediction of occupants' egress behavior during building fires with computer simulation.
