摘要
提出了线性损伤 -应变耦合模型 ,可计算结构损伤场随荷载变化的全过程 ;给出了考虑损伤行为特征的混凝土结构温度应力仿真计算方法 ,并对混凝土拱坝进行了考虑损伤后的温度应力仿真计算 ,从而为复杂混凝土结构的真正仿真分析研究奠定了理论基础。
A linear damage strain coupling model to analyse the damage of concrete structure is established and accumulated damage of concrete structure under varied loading is calculated with the model. The paper presents imitating method of thermal stresses with damage and calculating procedure of thermal damage stresses in concrete arch dam. The result expresses that imitating calculation of thermal stresses with damage is more reasonable.
