为提供框架-核心筒结构构件有效的震后损伤评价及修复方法,采用混凝土材料塑性耗能作为衡量指标,依据结构构件的重要性进行分类,分别研究了不同构件的损伤分布模式,并采用材料损伤定义不同构件的损伤指标,最后利用有限元软件ABAQUS对一简化模型进行动力弹塑性分析,将数值模拟得到的各类构件损伤分布结果与相应损伤分布云图对比,证明了该方法的有效性。
In order to provide an effective post-earthquake damage assessment and repair method for the frame-core tube structure, the plastic energy dissipation of the concrete material is taken as a measure to classify the components according to the importance of the structural components. The damage distribution modes of the different components are respectively studied, Damage definition of different components of the damage indicators, and finally the use of finite element software ABAQUS on a simplified model dynamic elasto-plastic analysis of the numerical simulation results of various types of damage distribution components and the corresponding damage distribution cloud comparison shows the effectiveness of the method.
