在预应力混凝土结构中。存在着许多模糊因素.比如说,预应力混凝土的分类、结构反应和设计目标都具有明显的模糊性。文献[1]按预应力度设计预应力混凝土结构,克服了加筋混凝土分类中存在阶梯断点的不连续现象。但其预应力度值选择时所考虑的因素不够完全。本文提出的方法较文[1]推荐的方法更直观,易于接受,且考虑了模糊因素,较文[1]方法更合理些。 In prestressed concrete structures. There are many obscure factors. For example, the classification, structural reactions, and design goals of prestressed concrete all have obvious ambiguities. In [1], the prestressed concrete structure was designed according to the prestressing degree, which overcomes the discontinuity of the step breakpoint in the classification of reinforced concrete. However, the factors considered during the selection of the prestress value are not complete. The method proposed in this paper is more intuitive and easier to accept than the method proposed in [1], and takes into account the fuzzy factors, which is more reasonable than the method [1].
