在1995年及1996年期间，一项主要的防火测试计划在一幢全尺寸的八层钢架建筑物上进行。这些测试的主要目的是研究钢结构建筑在一系列局部火灾下的实际行为。本文介绍了由建筑研究所进行的两项测试的结果。测试结果表明，现有的消防规范并没有解决火灾时建筑物的正确行为，因此非常保守。此外，对全尺寸框架的火灾试验表明，建筑物的实际整体和局部结构行为是不同的，而且通常要好得多；比标准小规模火灾试验显示的要高。本文详细讨论了在火灾试验中观察到的建筑物的行为，并提出了初步结论。
Synopsis During 1995 and 1996, a major fire test programme was conducted on a full-scale eight-storey steel-jiramed building. The principle aim of these tests was to investigate the actual behaviour of a steel-jiramed building subjected to a series of compartment (1ocalised)fires. This paper presents the results from two of these tests, which were conducted by the Building Research Establishment. The results from the tests showed that existingfire Codes are not addressing the correct building behaviour during afire and, as a consequence, are extremely conservative. In addition, the fire tests on the full-scale frame showed that the actual global and local structural behaviour of buildings is different, and typically far better; than that shown in standard small-scale fire tests. The paper discusses in detail the behaviour of the building observed during the fire tests, and preliminary conclusions are presented.
