关于火灾温度对建筑结构的材料力学性能的影响问题,在过去卅多年中,各国都进行了大量的试验研究工作,取得了大量数据,其中大部分是在试验室稳定温度条件下进行的,其试验方法和材料种类都不一样。因此,各国所作试验结果差别也较大。但不管 With regard to the effect of fire temperature on the mechanical properties of building structures, in the past more than 30 years, many countries have conducted a large number of experimental research work, and obtained a large amount of data, most of which are conducted under stable temperature conditions in the laboratory. Test methods and material types are different. Therefore, the results of the tests made by various countries are quite different. But regardless
