摘要
本文建立了一种用于分析三维钢筋混凝土结构的钢筋混凝土实体等参元,在这种单元中,钢筋是直接包含在混凝土中作为整体来考虑的,因此用这种单元作为有限元模型具有节点数少、离散化方便,而又具有精度高和能反映钢筋作用的优点.通过用本文编制的程序计算及与理论解和其它数值解的比较,证实了这种单元的有效性.
In the paper, a isoparametric quadrilateral solid element used for analyzing three dimensional reinforced concrete structure has been established, in which steel is considered to be directly involved in concrete element. Taking the element as finite element model has the advantages of reducing number of nodes, simplifying discretization, improving accuracy and being able to reflect effect of the steel. By passing programm calculation and being compared with theoretical and other numerical solutions, it is verified the effectiveness of the element.
