In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. In particular, calculation of evacuation capacity in evacuation safety design of buildings is the most important factor that directly affects 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, the purpose of this study is to study the current status and related regulations of the life safety code for the application of high fire risk buildings, and to analyze the difference in evacuation time through Case Study.

National performance-based design methods and prescribed standards for various input data not defined as separated regulation, ASET and RSET fire and evacuation simulations on the data cited by different designers. This is also directly connected reliability problems for the evacuation simulation and performance-based fire. standardizing the various input to performance-based fire and evacuation simulations of a similar risk, regardless of the experience of designer or technical skills. The performance-based targets proper fire-fighting and emergency equipment installed reasonable initial investment cost to done ensure safety.

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 case of fire in the high-rise buildings, the appropriate and safe evacuation plans for the building residents are very important to minimize the number of casualties. Since the evacuation time usually depends on the floor plans of the buildings, the evacuation plans should be considered while the architectural design is done. Conventionally, the calculation of the evacuation time in the case of fire breakout is based on the approximate mathematical equations which are prone to error. In this study, the simulator model is developed to help the architectural designers to access the more accurate evacuation time and find out the floor plans which offers the most safe evacuation plans for the residents in case of fire.

Today, building constructions are becoming larger, higher, deeper, and complex to improve quality of human life and meet various needs. As a result, new design space for non - typically standardized space has been created, and targets for performance-based design are also becoming increased. An evacuation safety evaluation of performance-based design should be compared with ASET and RSET estimation so that the value of RSET does not exceed the value of ASET. However, there is a problem that it is difficult to secure the safety with using the performance-based design evaluation method currently in use, especially in case of the underground parking lot, because it has wide compartment area and various routes for evacuation. Therefore, in order to overcome these problems, this paper first investigates the simulation setting method of the performance-based design that is currently in use, and then conducts two fire simulations and three evacuation simulations for underground parking lots each time, so performs the evacuation safety evaluationin total six cases of situations. Here this paper analyzes the problem with comparative evaluation research and suggests the better solution for improved evacuation safety evaluation of performance-based design.

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.

Fire resistance performance and performance design of fire doors are becoming more important to prevent the spread of fire and support the rapid evacuation of apartment buildings. In this study, a database using 182 evacuation spaces and 308 common areas that passed the fire performance test was established, and fire door performance influencing factors were derived through an analysis of the structure(12 elements) of the fire door. As a result, the effects of fire-resisting filler density, adhesive, and foam gasket were confirmed for evacuation space, and the effects of fire-resisting filler, adhesive, and fire fins were confirmed for common areas. In the fire door fire resistance test, flames and cracks were analyzed as the most frequent failure factors.

In the disaster prevention design, it is important point to secure escape way at event of fire which makes people away from the fire more quickly and safely. Development of construction techniques leads to build many skyscrapers, and skyscrapers contains various dangers and increase levels of disaster. At basic design stage for skyscrapers, evacuation scenario is considered that occupants are escape using escape stairs and emergency elevators simultaneously at fire, but there is no evacuation program to simulate using escape stairs and emergency elevators at the same time. In this study, evacuation simulation is performed using method of VR which is based on Virtools of 3DVIA Co., and Simulex of IES Co. for safety and effectiveness where occupants are escape using escape stairs and emergency elevators simultaneously at the fire.

As the rapid and various changing of social aspects, the structures are getting bigger, higher and more complex. The importance of evacuation is on the rise as increased using frequency of multiplex area and it's high population density. According to the result of a survey with 2 domestic multiplex population density, the maximum was 0.43(人/$m^2$) and 0.51(人/$m^2$). considering evacuation dangerousness, the maximum value will be suitable for computation of evacuation capacity and this will be submitted as a basic data for computation of evacuation capacity.
