With rapid growths of economy and technology, structures and forms of buildings have been diversified and complicated. Buildings also have become higher and larger than ever before. As a result, more people use a building and more combustibles exist in the building. Without understanding of combustion characteristics and the establishment of a fire safety plan in case of a residential fire, it is expected great loss of lives and properties. In this study, experiments were carried out to promote an understanding of the combustion characteristics of combustibles in the building. Sofa and bed were used as combustibles in the experiment. Heat release rate of the sofa was about 1.9MW. Heat release rate of the bed was approximately 650kW.

The movement towards sustainable building design can result in unique fire protection challenges and concerns, especially with super tall buildings in relationship to traditional prescriptive code compliance. Different countries haves different code requirements as well as local best practices and may cause conflict with the design features when designing green buildings. These include, but not limited to green roofs, sprinkler water quality and testing, fire department access and areas of refuge with direct or indirect impact by the perspective code compliance. The solutions to these prescriptive code challenges and fire safety concerns can range from simple alternatives to more detailed engineering performance-based design analyses with good solid practice.

Gypsum is an important building material used to provide fire resistance to constructions by reducing their temperature rises. As the hardened gypsum is exposed to fire, evaporation of both the free water and the chemical bond water is easier than that in the cement extruding panel. The purpose of this study is to investigate the utilizability of alpha-hemihydrate gypsum to prevent spalling failure of cement extruding panel exposed to fire. This paper reports the fire-resistance property of a controled general cement extruding panel(C100), and gypsum-cement extruding panels(C50A50, A100) according to replacement ratio of alpha-hemihydrate gypsum. As a results, it is found that A100 and C50A50 are more effective to prevent the explosive spalling failure under standard fire condition than C100.

A comparative study on the prevention regulation of historical heritage between Korea and Japan. Every years fire accident to historical building is increasing such as Daewoongjun, Naksansa, Namdaemun and so on. The aim of this comparative study is to investigate and compare the prevention regulation in the side of fire safety of historical building between Korea and Japan. This study focus on the background of development and exchange of Fire safety law in Japan because of same condition, building material and prevention regulation.

Korea rapidly arranged urbanization and overpopulation with high growth of economy and all kinds of decrepit facilities are scattered all over the downtown. If there is a strong wind in fire, fire is rapidly increased by various fire spread factors. And Korea cannot build prediction model of urban fire combustion phenomena because there is no studies that physically explains the suitable flame phenomena for its real state. In this study, for development of Korean Urban fire Simulation on Attenuation of Radiant Heat Flux from Water Screen.

Contrast a general building high rise buildings itself has a kind of risk. In this study, the risk of a number of high rise buildings have fire fighting safety management of the particular risks associated with looking for ways to minimize focused. Issues include self fire protection. disaster management, building code and fire code of the mismatch, such as fire protection facilities aspects are explained in terms of three kinds, and for it to take steps in the direction suggested an alternative for high rise buildings. Although differences of opinion between departments will not be easy to fire fighting and building codes regarding conflicts of codes above all require immediate resolution, and high rise buildings to create a standard for effective risk management manual countermeasures will also be ensured.

In Korea, smoke control measures through NFSC 501 are proposed to reduce human casualties caused by smoke in the event of a fire. However, as a result of investigating and analyzing domestic and foreign standards, it was found that domestic regulations do not set fire source, but simply set smoke emissions by floor area or height of smoke boundary. Foreign regulations set fire source. Therefore, it is judged that it is necessary to review whether the current domestic regulations can be applied in the event of an actual building fire. So, this paper aims to identify the differences in domestic and foreign standards through investigation and analysis of related standards for fire zone smoke control system in each country and use them as basic data to improve the performance of zone smoke control system.

Many pressurization systems are designed and built with the goal of providing a smoke-free escape route in the event of a building fire. A secondary objective is to provide a smoke-free staging area for fire fighters. In the present study, a computer program is developed to calculate pressure loss and flow rate at several building elements such as a room, a ]tabby a staircase and an air supply shaft. By the program as the dosing tool for the pressurization system, the capacity of the injection fan is calculated, and the design method is proposed for the optimization of the fan capacity.

There are many economic and operational reasons to integrate fire alarm signaling system with other building automation system. Integration of this requires communication standard and careful design practices. The important point for this is also the development of intelligent control modules for replacing the conventional zone adapter in fire system. Therefore, this paper proposes an new conceptual design of the distributed fire alarm signaling system and a new intelligent control modules with LonTalk protocol. Newly proposed additions to LonWorks network make it very well suited for integrating fire systems with other building automation systems. Additionally, it is very important that best design practices, test procedures and building codes need to be modernized to accommodate Integrated building systems.

The fire in Ulsan in 2020 was a 33-story residential and commercial complex with about 90 injuries and more than 10 billion won in property damage, and considering the recent increase in high-rise residential and commercial complexes, the risk of similar fires is high. As can be seen through the residential and commercial complex fire case in Ulsan, life-based fire safety standards need to be established to minimize casualties. Therefore, the purpose of this study is to draw improvements for the development of human safety standards for high-rise residential facilities in the future through comparison with the Korean Building Act, Firefighting-rellated Acts and the U.S. NFPA 101.
