摘要: 简述了一个RC框架顶层端节点在ABAQUS中的建模过程。采用混凝土损伤塑性本构模型,对节点模型进 行了单调加载下的有限元分析。通过非线性分析结果与实验结果对比,研究了顶层端节点的受力机理,考察了混 凝土强度,纵筋强度,配箍率等因素对节点受力性能的影响。

关键词: 顶层端节点, 损伤塑性模型, ABAQUS

Abstract: The modeling of a knee joint in reinforced concrete frames is described in ABAQUS software. The joint model using concrete damaged plasticity model is analyzed under continuous load by using ABAQUS. Through the comparison between the results of nonlinear analysis and the tested results, the force mechanism of the knee joint is studied, and the effect of concrete strength, strength of longitudinal reinforcement and stirrup ratio on mechanical behavior of knee joints is also examined

Key words: knee joints in reinforced concrete frames, damaged plasticity model, ABAQUS
