| Summary: | 碩士 === 高苑科技大學 === 建築研究所 === 99 === In recent years, the high-rise buildings tend to get much higher, more underground and complex. However, in the planning and design processes, the high-rise buildings are often required to merely meet the basic provisions of the laws and regulations due to structural considerations. As for fire, heat and toxic smoke, the two-direction emergency escape is discussed. This paper mainly aims to enhance the design requirements of fire protection facilities for high-rise buildings so as to ensure the personal safety of people in high-rise buildings.
The high-rise office building is placed with a number of materials and electric equipment spatially, such as documents, computers, etc. Therefore, the “fire”, “heat” and “toxic smoke” and other related factors shall be considered during the assessment, and partial designs may not meet the safety evaluation of fire protection and emergency escape. It is an important subject today to find the ways to promote the safety of high-rise buildings’ rooms and space as offices.
This paper studies the high-rise buildings with more than 16 floors or office buildings with a height of more than 50m, and quantizes the assessment on rooms and space for office uses. Through summarizing the features of all rooms for office uses, the safety performance of fire protection and emergency escape are analyzed so as to find the reference point for fire protection and emergency escape. The conclusions are as follows:
Based on the study and analysis about factors affecting fire protection and emergency escape, such as room area, exit width, fire resistance rating of interior decoration materials, average ceiling height, etc, all factors are assessed with 1m3 smoke volume as the datum so as to validate the emergency escape performance of the room.
When the net area of rooms and space for office uses reaches more than 150m² (interior decoration materials are above the fire resistance rating II, the average ceiling height is 2.8m, the heat release is 560MJ/m highly², and the personnel density is 0.3 capita per m²), the second escape exit with a width of more than 90cm shall be set to meet the requirements for fire protection and emergency escape.
In the planning process of offices of high-rise buildings, the research results obtained by the paper, to some degree, can facilitate the determination that whether more than two emergency escape directions shall be set along the path for emergency escape so as to meet the principle of safe emergency escape.
