| Popis: | 99 With the continued break troughs of construction technology and the increase of high-rising, compound buildings with large scale space, the existing regulations have been not be able to meet the requirements of modern buildings, and even the worse, the norm of regulations could limit the development of building. Therefore, many countries in the world have developing functional regulations to overcome the obstacles made by existing regulations for the development of modern construction technology. In Taiwan, the authorities have implemented functional regulations to respond since 1984. The parts of fire separation of construction technology rules are even better to break through limits and expand the scope of fire separation by the functional regulations. This research aims to break through the limits of regulation in expanding the scope of fire separation to satisfy the demand for greater space from large shopping malls and shopping centers by designing the sense of space that the lofty part of building wants to express and increasing freedom of design. Secondly, the assessment of practical cases, Fire burning by a variety of experimental literature measured data(Such as temperature, flame height, heat radiation), With the FDS computer simulation software and fire spread between theoretical analysis of the formula, Factor of the difference, Terms of the presence of simulated radiation, Explore the theoretical formula by comparing the difference with the simulation software Factor to simulate the results of calculation of factors, Parameters of the simulation results and adjust the fire burning again with a comparative analysis of experiments, From the analysis results show that Fixed fraction of thermal radiation from lower in the theory of the radiation formula, Then consider the heat release rate curve, Heat release rate will be fixed to the maximum, Discussion to the limit of heat radiation, The simulation results with the theoretical formula of heat radiation from the relatively close. |
