可拓评价方法的改进及其应用研究

Research on assessment of building fire safety by improved extension assessment method

将可拓工程方法与高层建筑中对火灾风险有影响的因子相结合,建立了高层建筑火灾风险评估的可拓评价模型。首先在该模型中对原可拓评价方法进行了修正,提出了最大贴近度法与最大对比度法。其次在原可拓评价方法的基础上首次建立了多级可拓评价模型,解决了用可拓评价方法进行多因素评价的问题。最后对高层建筑火灾风险评估进行了实例分析,根据实际情况采用可拓方法选取权重,并与文献中已有的权重进行比较,结果表明在不同权重下的评价结果基本一致.

By means of combining extension assessment method with fire safety influencing factors for high-rise buildings, extension assessment model is established to evaluate fire safety of high-rise buildings. In the model, extension assessment method is improved; as maximal adjacency degree and maximal contrast, and multilevel extension assessment are first discussed. An application example is studied for a high-rise buildings; it is shown that their assessment results are consistent in same method based different factor weights.
