Currently in domestic, it is difficult to the evacuation in fire due to the building is higher. Therefore it is necessary to evacuation safety design of building. To conduct the evacuation fire design of building, it should be done the Evacuation Safety Verification. But it is not sufficient the Study about Evacuation Safety Verification in currently domestic. Therefore in this study, we conducted the evacuation safety verification using people who they can't the evacuation themselves. The method of verification, we suggest the comparative that people who they can't the evacuation themselves and available safety evacuation time. Available safety evacuation time is determined by determined method from disaster statistics of casualties or equivalence with current standard requirement. it is doing to objectively judge of evacuation safety design validity in building.

Recently, According to increased tunnel accident, a matter of concern in tunnel fire safety is on an interesting trend. In case of tunnel fire, Evacuation is a primary factor for refugee safety. Therefore safety measures should be taken to increase capability of evacuation. Evacuation walking speed and characteristics of movement in tunnel is differ from building or outdoor site so, these characteristics must be considered in tunnel safety planning. In this study has performed to evaluate the smoke movement and characteristics of evacuation by full-scale test method. and aimed for basic data establishment in characteristics of evacuation for tunnel safety system design.

The purpose of this study is to propose measures to increase evacuation safety by calculating the habitable time using a fire and evacuation simulation program for the Room-escape cafe currently in operation, and comparing and analyzing it with the evacuation required time. Assuming a fire due to overheating of electric heaters in use in front of the warehouse, the habitable time was calculated through fire simulation, and the occupant's evacuation time calculated through evacuation simulation according installation of safety facilities, etc. was compared and analyzed with the habitable time. In the case of escape room cafes with safety facilities installed, evacuation safety was satisfied, but in escape room cafes without safety facilities, the evacuation safety was not secure. As a result of analyzing evacuation safety for each scenario based on the ASET analyzed in the fire simulation, it was found that in scenario 1, evacuation safety was secured and everyone successfully evacuated, while in scenario 2, no one succeeded in evacuation. These results can be said to confirm that the installation of safety facilities is very important in business establishments such as escape room cafes, which become enclosed structures when games are started.

In this study, it was analyzed by a numerical analysis that plan/design considerations for ensuring the spectator safety of large arena audiences in a fire emergency evacuation plan. The latest issue, the 'performance-based design', fire and evacuation plan is important. But nowadays 'Specification-based design' is in common. In evacuation simulation, congestion of exit and aisle is ignored because only evacuation time of large-space is mainly analyzed. In smoke flow,'smoke filling effect' tends to be overrated. From now on, when design a field house, it is needed not 'smoke filling effect' and 'large-space evacuation' analysis, but analyzing 'whole building evacuation time' for ensuring fire evacuation safety of spectator.

There is a need to analyze various factors in evacuation safety assessment of building in fire. In the current performance based design, evacuation safety assessment in case of fire is being conducted through the simulation as FDS and Pathfinder. However, the location and size of the door, the location of evacuation in the event of a fire are not considered when design. Accordingly, it is difficult to determine the worst case scenario considering the actual fire. Therefore in this study, in this study, we will propose an appropriate evaluation plan through simulation considering the worst-case scenario that may occur in case of fire.

When evacuation safety Design of buildings, the calculation of evacuation capacity is the most important factor that it directly impact of evacuation safety performance. However domestic standards is not consider about occupant characteristics. also the case of domestic, it has the problem that the law is partially applied when the fire safety design of buildings. Therefore, in this study we anlayze the evacuation capacity standards of each countries as basic study for development the Korean Life Safety Standards

오늘날 인간의 삶의 질 향상과 다양한 욕구를 충족시키기 위한 건축물은 대형화, 고층화, 심층화, 복합화 되는 추세이며, 이에 따른 비정형화된 공간이 새롭게 창출되면서 성능위주설계대상도 증가하고 있다. 성능위주설계의 피난안전성 평가는 ASET과 RSET를 산정 비교하여 RSET이 ASET를 초과하지 않도록 하여야 한다. 그러나 지하 주차장과 같이 구획된 공간의 면적이 넓고 피난경로가 다양한 경우 현재 시행되고 있는 성능위주설계 평가 방법만으로 모든 피난경로에서 안전성을 확보하기 어려운 문제가 있다. 따라서 본 논문에서는 이러한 문제점을 극복하기 위해 현재 사용되고 있는 성능위주설계의 시뮬레이션 설정방법에 대해 먼저 고찰한 다음 지하 주차장을 대상으로 화재시뮬레이션 2가지와 피난시뮬레이션 3가지 경우를 각각 수행하여 6가지 경우에 대한 피난안전성 평가를 실시하고 비교 평가하여 문제점을 살펴보고 개선된 성능위주설계의 피난안전성 평가 방안을 제시한다.

In recent years, the frequent occurrence of fire accidents in university libraries has posed significant threats to the safety of students' lives and property, alongside negative social impacts. Accurately analyzing the factors affecting evacuation during library fires and proposing optimized measures for safe evacuation is thus crucial. This paper utilizes a specific university library as a case study, simulating fire evacuation scenarios using the Pathfinder software, to assess and validate evacuation strategies and propose relevant optimizations. Pathfinder, developed by Thunderhead Engineering in the United States, is an intuitive and straightforward personnel emergency evacuation assessment system, offering advanced visualization interfaces and 3D animation effects. This study aims to construct evacuation models and perform simulation analysis for the selected university library using Pathfinder. The library's structural layout, people flow characteristics, and the nature of fire and smoke spread are considered in the analysis. Additionally, evacuation scenarios involving different fire outbreak locations and the status of emergency exits are examined. The findings underscore the importance of effective evacuation in fire situations, highlighting how environmental conditions, individual characteristics, and behavioral patterns significantly influence evacuation efficiency. Through these investigations, the study enhances understanding and optimization of evacuation strategies in fire scenarios, thereby improving safety and efficiency. The research not only provides concrete and practical guidelines for building design, management, and emergency response planning in libraries but also offers valuable insights for the design and management of effective evacuation systems in buildings, crucial for ensuring occupant safety and minimizing loss of life in potential hazard situations

Human and material damage can be reduced if the risk is evaluated by engineering analysis of fire combustion products, smoke concentration, and smoke movement speed in the event of a fire in apartment houses and officetels. In this study, a lot of research on related safety evaluation in the basement needs to be studied and reflected in design, so experimental research was conducted to analyze the flow of smoke through computer simulation and provide analysis data through evacuation safety evaluation. First of all, the five-story underground parking lot subject to simulation has a large floor area, which is advantageous for improving evacuation safety performance, but it uses temperature detectors to increase detection time and fire spread speed. Second, it was analyzed that the evacuation time at all evacuation ports did not exceed the evacuation time, and as the time from the start of evacuation to the evacuation time was 216.9% compared to the travel time, it was evaluated that the safety performance of the evacuation was secured. Third, the above simulation results are a comprehensive safety evaluation based on the non-operation of fire extinguishing facilities in the fire room to increase safety, which means that smoother evacuation safety performance can be secured by linking fire extinguishing facilities.
