摘要:
针对现有钢筋混凝土平面单元模型所存在的问题,建立了在各种配筋形式下钢筋混凝土平面问题四边形单元组合模型,导出了这些模型的单元刚度矩阵的一般表达式.与弥散单元模型的对比分析表明,组合单元模型不仅符合有限元离散的基本理论,而且可较精确地反映钢筋的实际结构作用,具有较强的实用性.
Abstract:
Aiming at the problems existing in the existing reinforced concrete plane element models, the combined model of the reinforced concrete plane problem quadrilateral elements under various reinforcement forms is established, and the general expression of the element stiffness matrix of these models is derived. The comparative analysis with the diffusion element model shows that the combined element model not only conforms to the basic theory of finite element discretization, but also can accurately reflect the actual structural effect of steel bars, which has strong practicability.
