摘要
针对现有的三种钢筋混凝土有限元模型(整体式模型、分离式模型、组合式模型),结合影响钢筋混凝土结构性能的部分因素,运用大型商务有限元软件ABAQUS对矩形截面的悬臂梁钢筋混凝土结构进行仿真分析。结合现行《混凝土结构规范》采用的最小刚度法,重点对比分析三种模型在适筋范围内配筋率与挠度的关系,从而得到不同模型在不同配筋率情况下的优缺点与适用性,为受拉构件钢筋混凝土结构有限元模型的选取提供一定的参考。
Aimed at the three kinds of models of reinforced concrete finite element which are assembled model, smeared model and discrete model; combined with some factors that are affecting the performance of reinforced concrete structures. This paper conducted simulation analysis for reinforced concrete cantilever structure of rectangular cross- section by using ABAQUS finite element analysis software. Combined with the principle of minimum rigidity in Concrete Structure Specification,it focused on comparative analysis about relationship of reinforcement ratio and deflection within the appropriate range of reinforcement ratio for the three finite element models,which comes out the advantages and disadvantages as well as the serviceability of three finite element models at different reinforcement ratios,also it provides a reference for selecting the models of tension members reinforced concrete finite element.
