摘要
本文根据Ｎａｊａｒ损伤理论，提出了一种应用于混凝土构件损伤分析的分段线性化模型．文中给出了这种模型的损伤列式和有限元计算方法。数值算例表明，这种方法有较好的精度，可以在混凝土结构损伤分析中应用．
With the aid of Najar damage theory,a new modified linearized damage model for concrete members is proposed inthis paper.The relevant damage formulas and calculation method of FEM are also given.Numerical results of a concretebeam show that the proposed damage model in this paper is very accurate and may by applied to the damage analysis ofconcrete structures.
