| 摘 要： | 通过分析影响钢筋混凝土构件耐久性损伤的原因,结合钢筋混凝土构件耐久性损伤的模糊性和随机性,选用了模糊概率评估模型,将钢筋混凝土构件耐久性状况划分成4个等级,选取了5个影响构件耐久性的主要因子,先对各个影响因子进行单因子评价,并选用正态分布作为各影响因子的隶属度函数,对钢筋混凝土构件耐久性状况进行评估。通过工程实例验证表明:通过对模糊概率评估模型评估结果与模糊综合评判法预测结果进行对比,用模糊概率评估模型进行预测,更接近于实际情况,说明了该模型不仅为钢筋混凝土构件耐久性状况的评估问题提供了一种新途径,而且该方法比传统的模糊综合评判法更优越。 |

| Abstract: | By analyzing the reason which affect durable injury of reinforced concrete members,combined with the fuzzy and randomicity of the durable injury of reinforced concrete members,assessing the durable state of reinforced concrete member with the fuzzy probability model.Durable state of reinforced concrete members were divided into three grades,in this model,five factors which affect durability of reinforced concrete members were selected,each of these factors was assessed.The function of normal distribution wa... |
