摘要
通过分析若干结构工程设计遇到的困难和钢筋混凝土有限单元法的优势,指出钢筋混凝土有限单元法应用于水工结构设计与分析是十分必要的,也是十分有效的.通过对本构关系、单元模型、裂缝模型、材料强度和荷载取值等关键问题的讨论,提出了应用钢筋混凝土有限元法进行水工结构设计时应遵循的计算原则.
From an analysis of some difficulties occurring in the design of several hydraulic structures and the advantages of the reinforced concrete finite element method （RCFEM）, it is concluded that RCFEM is necessary, applicable, and effective for design and analysis of hydraulic structures. Based on a discussion of some key problems in structural design, such as the constitutive relationship, element model, crack model, material strength, and load determination, the calculation principle, which should be followed in hydraulic structure design with RCFEM, is presented.
