基于本构模型钢筋混凝土简支梁有限元分析

Finite Element Analysis on Reinforced Concrete Simple Beam Based on Constitutive Model

针对有限元法在结构工程中的应用,采用美国E.Hognestad模型,利用ANSYS建立应力-应变关系,通过计算实例,对钢筋混凝土简支梁在荷载作用下,应力应变对混凝土的损伤进行数值分析。

Combined with the applications of finite element method in structural engineering,stress-strain curve is established using ANSYS with the United States E.Hognestad model in this paper.The calculation shows that the damage of reinforced concrete simply supported beam under load caused by stress-strain is modeled.
