钢筋混凝土平面单元研究

Study of the Finite Element of Reinforce-concrete

对目前已有钢筋混凝土有限元模型进行了研究分析 ,指出了这些模型存在的问题 ;同时 ,建立了较符合结构实际和材料的力学性态的钢筋混凝土有限元模型 ,导出了这些模型的单元刚度矩阵 .这里 。

The analysis on existing models for finite elements of reinforce concrete and its shortages are presented. New finite elements of reinforce concrete which is suitable for practical structure and material quality are set up. The rigidity matrix for each type of the elements is worked out.
