| 摘 要： | 高强混凝土的应用前景越来越广阔,针对火灾造成的高强混凝土损伤,急需建立科学的检测与评价方法.以模糊理论为基础,结合无损检测方法,分别以抗压强度损伤系数、耐久性损伤系数与外观损伤系数为一级评价指标,爆裂度和裂缝宽度为外观损伤的二级评价指标,采用聚类矩阵特征向量法确定评价因子的权重,建立了模糊综合评价计算模型.并设计了相应的程序,通过实例进行了验证.

| Abstract: | With application prospects of high strength concrete(HSC) being more and more vaster,scientific method of examination and evaluation on damage of HSC caused by fire is need to be built up.Based on fuzzy theory and combined of non-destructive examination,a computational model of fuzzy comprehensive evaluation is put forward in this paper.Strength damage coefficient,durability damage coefficient and external appearance damage coefficient are the first grade evaluation indexes.In addition,the spalling degree a... |
