【摘要】 本文从建立钢筋混凝土结构的计算模型开始,讨论了钢筋与混凝土的离散,混凝土的裂缝模型、本构方程、破坏准则等内容,并用所讨论的模型和破坏准则,对一钢筋混凝土梁进行了计算分析。最后与试验结果作了比较,验证了分离式钢筋混凝土结构有限元分析的计算方法和可行性。更多还原

【Abstract】 This paper discusses the discretization of steel and concrete, crack model of concrete, constitutive equations and failure criterion etc, from beginning with building reinforced concrete structures modeling. Analysis of a reinforced concrete beam using above models and failure criterion is performed secondly. At last ,this paper compares numerical modeling with experimental load-deflection responses in order to confirm the feasibility of discrete model.更多还原
