Research Of Performance-based Fire Safety Design Of High Rise Office Building

High-rise office building is not only the product of social progress and thedevelopment of times, but also one of the greatest symbol of human society intwentieth century. Along with the economic and technological development levelenhancing，both the quantity, size or quality of construction, are constantly scalingnew heights. The beautiful skylines sketched out by high-rise office buildings inbustling cities, confirms the prosperity of world economy. The high-rise officebuilding development, which is under the background of Chinese society, isgradually catching up with the pace of developed countries, and continuouslyexploring the experience of office building given by architectural technology and artin new era. At the same time, people begin to pay more comprehensive concern andattention to the safety issues of these buildings in new era. It constitutes a greatchallenge that the fire safety design of high-rise buildings, for the reason that thecombined effects of spatial characteristics, functional composite, the new space, newmaterials and other aspects of the introduction.Following the relevant national code regulations strictly, the traditional firesafety design method of high-rise office building approach independently. Currentnational code is not conducive to the development and application of new space, newmaterials, new technology for their limitations, furthermore, it often overlooked thesynergistic effect of building fire safety design under the combined effects of thevarious subsystems of building. As the most advanced technology in fire safetydesign field, performance-based fire design has more applicability and flexibility forthe needs of fire safety design in new era. Thus, it would be a very valuable researchtopic that the research of performance-based fire design for the high-rise officebuildings in new era, solving the difficulties of fire design through the explorationand application of performance-based fire design theory, enhancement of thecomprehensive fire safety, avoiding and reducing the dangers of building fire, finallyrealizing the optimal design combine with building function, the arts, the security andeconomic interests. Mainly in architecture perspective, this dissertation summarized the spacecomposition and the characteristics of building fire according to high-rise officebuildings. On this basis, it selected several difficulties and emphasis of thesebuilding’s typical architectural space, construction and facility design, focused onanalysis performance-based fire safety design based on modern digital technology,put forward several design strategies which has pertinence and practical significancecombined with existing specifications. Furthermore, it provided several scientificdesign basis of fire safety design, avoiding the increase of subsequent correctiondifficulty. At the same time, this paper would expand the new fire safety designconcept and knowledge in architectural field, promoting the cross and integration ofacademic disciplines.This paper is divided into six chapters, respectively introduced the researchbackground of the issue and relevant literature review, the summarizing of high-riseoffice buildings and fire-related content, the research of performance-based firedesign theory. Furthermore, it studied the high-rise office building space and typicalstructure of performance-based fire protection design from macro, meso and microlevel. In architecture perspective, this paper not only discussed the concreteapplications of performance-based fire safety design in solving the high-rise officebuilding fire protection design difficulty from both theory and practice aspect, butalso summarized the design strategies which has practice value.
