In case of fire in the 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 stairs and passages of design of the building, 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 simulation software is developed to help the architectural designers to access the more accurate evacuation time and find out the floor plans which offers the most sage evacuation plans for the residents in case of fire.

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.

In case of fire in a compartmentalized building area, a number of casualties are caused by smoke production. Accordingly, openings, penetrations and joints in compartmentalized spaces should be secured not only for fire resistance but also for smoke-proofing. However, domestic test regulations stipulate test methods for refractory performance of penetrations and joints, but do not specify separate deferral performance. In the case of openings, the test for the smoke performance exists at room temperature, but the smoke performance at high temperature is not secured, so countermeasures are needed.

In order to minimize casualties in case of a fire in a building, it is necessary to anticipate the time required for evacuation of occupants and the delay in evacuation in advance, and prepare countermeasures for possible occurrences. In fact, various factors that cannot be predicted exist and cannot be considered by excluding them, so the risk is predicted and evaluated through quantitative evacuation modeling. In order to understand this, we analyzed domestic and international evacuation modeling research trends. For about 40 years, starting with the characteristics of human movement, an evacuation modeling technique based on scientific methods has been developed through actual fire accident cases and various real-world experiments with humans. Then, in order to analyze the natural reaction of humans, which has a decisive influence in the recognition and decision-making phase, evacuation modelling studies have been conducted in depth using psychological and physical experimental methods.

In apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.

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.

As the distribution of vehicles and logistics increases due to the development of human civilization and the increase in population, various roads play an important role in domestic traffic and transportation. However, the recent emergence of large cities and new cities is causing traffic problems, and the increase in roads is inevitable for the smooth distribution of vehicles and logistics. In Korea, mountainous regions occupy 70% of the country, so tunnels are used to open roads. Without this, it is difficult to open the road. Currently, there are 3,720tunnels (as of December 31, 2023) installed on high-speed national highways, general national highways, and local roads nationwide, with a length of 2.499 and increasing every year. Accordingly, fire accidents in tunnels will also increase, and due to the nature of tunnel fire accidents, there is a high probability that they will escalate into large-scale disasters, resulting in casualties and property damage, as well as significant social losses due to the disruption of logistics transportation, etc. As the possibility of potential hazards is increasing, the purpose of this study is to build a safe and efficient tunnel system by optimizing maintenance and management for fire and disaster accidents in tunnels.

For the past decade, South Korea had experienced catastrophic building fires, which resulted in consider-ably high number of casualties. This motivated research to develop fire-safe wall assemblies. In this study Fire Risk Analysis (FRA) is conducted as part of the project designing phase to ensure fire safety of the final product. Traditional approach was to consider fire performance at the end of the designing stage, when PASS/FAIL fire test results are required to be submitted to the Authority Having Jurisdiction (AHJ). By applying a fire risk analysis to guide the designing phase, overall fire safety of a wall assembly can be achieved more systematically as conducting FRA allows designers to clearly identify elements that are more vulnerable to fire and simply replace them with other practical options. Severity of fire risk is determined by considering the fire hazards of a wall assembly such as the exterior layer, insulation, vertical connectivity, and external ignition sources (e.g., photovoltaic panels). Frequency of fire risk is assessed based on the factors affecting fire likelihood, which are air cavity and fire-stopping applied in the design, and random design changes occurring during on-site construction. Fire risk matrix is proposed based on these fire risk factors and efforts to reduce the fire risk level associated with the wall assembly are given by systematically assessing the fire risk factors identified from fire risk analysis. Current study demonstrates how fire risk analysis can be applied to develop fire-safe walls by reducing the relevant fire risks- both severity and frequency.
