【 摘 要 】

References(20)This paper presents survey results on fire loads distributions for hotel buildings in the cities of Hefei, Lanzhou, Shenyang, Chengdu, Yantai and Tianjin surveyed in China. Details of the survey methodology, data collection and processing are given. Furthermore, the influence of the hotel rating, room type, region and room floor area on fire loads are discussed in detail. Based on the probability statisticsand test of normality, the fire load densities of all the surveyed hotels show a lognormal distribution with the mean value of 349.2 MJ/m2, the maximum value of 886.4 MJ/m2, the minimum value of 117.8 MJ/m2, and the standard deviation of 142.1. The fire loads obtained from the survey have been compared with those of similar surveys in other countries. According to the survey results, the fire dynamical theory and characteristics of building fire, the evaluation methods of the fire duration time and the collapse probability of building caused by fire are also developed in this paper. The statistical parameters of the fire load presented in this paper will be useful in the design of fire prevention and fire fighting measures of hotel buildings.
