研究超强地震后混凝土屈曲关系剩余抗拉强度数值分析问题，为灾后恢复重建和建筑受损评估提供数据依据。分析震后型钢混凝土屈曲关系模拟分析与试件结构的屈服场效应，构建混凝土材料在地震后的初始损伤和自由退化数学模型，得到混凝土混合材料的弹性模量，进行混凝土弹塑性模型网格划分和边界条件分析。从试验角度得到地震后型钢混凝土屈曲关系剩余抗拉强度数值分析结果，得到地震作用后两组试件的受损云图，最后得到不同等级地震作用下的剩余抗拉强度与承载力数值分析结果。研究得出，该数值分析模型得到剩余抗拉强度数值分析结果准确可靠，精度较高，公式计算结果与数值模拟分析结果符合较好，有效构建地震后混凝土屈曲关系剩余抗拉强度关系。在灾后损伤评估与修复重建中优越的应用性能。

Analysis of the numerical relationship between concrete buckling super post earthquake residual tensile strength is researched, the damage assessment provides data basis for post disaster reconstruction and construction. Analysis of steel reinforced concrete flexion of the earthquake simulation analysis and test yield field effect structure, construction of con?crete material degradation model in the initial damage and free after the earthquake, the elastic modulus of concrete mixed materials, analysis of concrete elastoplastic model mesh and boundary conditions. The results of numerical analysis of steel reinforced concrete buckling residual tensile strength after the earthquake damaged images from the experimental angle, two groups of specimens obtained after the earthquake, the residual tensile strength and bearing capacity under different earthquake levels of numerical analysis results. The numerical model is obtained, the numerical analysis results are accu?rate and reliable, it has high precision, the simulation results accord well with the numerical results of the formula, it can ef?fective construct the relationship building concrete buckling residual tensile strength after the earthquake. The model has good application value.
