钢筋混凝土结构有限元网格剖分的一种方法

An Approach of Finite Element Mesh Generation for Armoured Concrete

本文将选用分离式模型对钢筋混凝土平面结构进行有限元网格剖分 ,其中对混凝土结构采用四边形网格的自动剖分方法 ,对钢筋则采用一维杆单元的生成方法。本文所述方法能保证所产生网格的质量 ,有利于钢筋混凝土有限元分析。

This paper will choose the separative model to generate the finite element mesh for the structure of the reinforced concrete. Thereinto, for concrete, we use an approach to automatical quadrilateral mesh generation, and for reinforcing l bar, the unit of one dimension staff is used. The approach in this paper can ensure the quality of the mesh and also make for the finite element analysis of the reinforced concrete.
