按钢筋混凝土框架结构的破坏状态诊断材料损伤参数

摘要

It was assumed that concrete obeyed the law of uniaxial Mazarsdamage constitutive model in this paper.One proper inversion target function was inducted.By fraction method and variable turn decreasing search range progressively method,which was put forward in the paper,one or more concrete damage parameters inversion analysis was carried out according to the state of destruction of reinforced concrete frame.It provides an effective way that material damage in structure will be analyzed by it.%本文假定钢筋混凝土框架结构在破坏过程中混凝土材料遵循单轴受力的Mazars损伤本构模型规律，引入适当的反演目标函数，具体运用分数法和本文提出的变量轮换搜索区间递减法对处于破坏状态的钢筋混凝土框架结构的混凝土材料的一个或多个损伤参数进行反演分析获得成功，从而为定量地分析结构中材料的损伤提供了有效的途径。
