摘要
运用ANSYS进行纤维筋混凝土梁结构非线性分析，探讨了混凝土和纤维筋的本构模型、单元特性以及有限元模型的建立。用非线性有限元分析方法可以给出纤维筋混凝土梁受弯时内力和变形发展的全过程，对于实际工程和科学研究具有足够的精度。
In this paper, the constitutive models of concrete and reinforcement, as well as the properties of their element and the models of concrete beams reinforced with FRP bars are discussed. By using nonlinear analysis of the concrete beams reinforced with FRP bars, forces and the whole process of deformation development are given. Meanwhile, the finite element model can provide more reactive information for structure circulation.
