According to the development of industry, many aspects of society have been changed and a living environment has been more convenient than before. However, factors of fire risk are increased because of society which is becoming complex. Moreover, a building built in recently is becoming high-rise and intelligent. Then losses of life and property increase continually. Thus, an institutional strategy which can solve this problem is needed. The purpose of this research is to state a problem of specific a building managing strategy and suggests a reformation of the fire safety grade system of a specific building. The suggested ideas are an adoption of fire risk evaluation of a building, tentatively named "Fire Safety Corporation" establishment, reclassification of the fire safety grade system of a specific building, and newly making fire safety managers of ultra-high buildings and underground structures.

As the fire inside the building grows rapidly, ejected flame from an opening occurs due to flashover. As a result, the number of cases where the flame spreads to the exterior of the building and rapidly expands to the upper floor is increasing. In particular, in the case of the fire in the Daebong Green Apartment, Uijeongbu in 2015, it was a case where the flame spread to adjacent buildings due to the opening eruption flame from the first ignited building, causing great damage to three apartments. Therefore, this study is to introduce an international standard under development that estimates the shape and properties of the ejected flame from an opening and quantitatively evaluates the radiant heat flux received by the exterior wall of the building by assuming the occurrence of the ejected flame from an opening.

Fire is one of the greatest threats to historical buildings not only to the building's occupants but also to the building's structure and contents. The purpose of this research is to evaluate fire risk in historical buildings in Korea through a series of survey and review. In this research, a multicriteria decision-making approach involving Analytical Hierarchy Process has been designed to determine a weighted index to identify factors and quantify fire risk. Fire risk ranking systems of historical building has been developed in some applications, for example, BOCA, WISCONSIN, FSES and HFRI. According to the such derived fire risk indexing, the Human Activity index showed the highest risk, followed by Historic Buildings, Fire Safety Systems, and then Natural Environmental Causes. Comparison of these factors indicates that the derived risk values differ from case to case. It is proposed that a performance-based design approach should consider the building & occupant characteristics, locations and historical significance, resulting in a more accurate and effective evaluation of fire risk.

Analyzed in the NFDS, The average number of fires in vinyl temporary buildings is more than 1,000 in annually. And the number of deaths and injuries was around 30 people in every year. According to the National Fire Agency, There are 142,386 vinyl temporary buildings for Agriculture and Fishery, of which 4,720 are residential vinyl temporary buildings in illegally. Model house is subject to regulation in fire-related law. But, even though it's the same temporary building, Vinyl temporary building is not subject to regulation. For this reason, Vinyl temporary buildings are left in the blind spot of fire safety. Therefore, In this study, We propose that amend of Act on installation and management of firefighting systems, make of temporary fire safety controller, develop and apply of alarm system that is connected to a single-alarm smoke dretector, organize and operate volunteer fire brigade of the crop group to prevent and extinguish the fire.

It was investigated fire resistance properties and mechanical properties of high strength concrete column using ECC(Engineered Cementitious Composites) permanent form by KS F 2257 Methods of fire resistance test for elements of building construction and compression test for application of precast concrete column method of high rise building in this study. As a test result, it was appeared that ECC permanent form is available as fire resistance method of high strength concrete and new precast concrete construction method for facilitating construction of high rise building.

This study aims to develop a current building condition database of an important folk culture village of South Korea considering their fire spread risk. We have selected a folk cultral village, and conducted field survey to reveal structure of buildings, materials of building wall, and roof style which make us understand current vulnerability of the village to fire spread. As a result, we made a current building condition database with map, which showed that the village had mixture of reinforced concrete and wood. Besides, we proposed a conceptual idea to prevent from large fire accident in the village.

The Combustion gas behavior induced by fire in a building is numerically investigated. The typical building for this analysis is partially divided by a vertical baffle projecting from the ceiling. The solution procedure includes the low Reynolds number ${\kappa}-{\varepsilon}$ model for the turbulent flow and the discrete ordinates method is used for the calculation of radiative heat transfer equation. The effects of the location and size of fire source and baffle length on velocity and temperature distributions, species mass fraction and flame location are analyzed. As the results of this study, it is found that the case when the fire source is located at the vertical wall is more dangerous than at the bottom wall in view of the combustion products and flame location. It is also found that the radiation effect cannot be neglected in analyzing the building in fire.

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. Therefore, the purpose of this study is to research status and related regulations of Life Safety Codes for High Fire Risk Building Applications In the future, using this as basic data, it is considered that additional research is need to development Human Safety Standards in Korea.

The fire that broke out in a residential and commercial complex in Ulsan in October 2020 was large, but no deaths occurred. For this reason, there was a difference from the previous cases, so it was analyzed through field survey. The fire was expanded to the entire building by aluminum composite panels constructed by external heat method and SMC panels in evacuation safety zones, and fire was expanded to nearby mart due to wind on the day of the fire, and there were many evacuation spaces such as 15th, 28th, and rooftop heliports.
