The damage models proposed to date fail to identify the damage transition within one typical dual structural system, that is, wall–frame structures, under strong earthquakes. It's conceptually promising to combine a macroscopic global damage model physically with a simplified structural model that can characterize the interaction mechanism between the frame part and wall part of the structures. Thus, a macroscopic approach, with the integration of a macroscopic global damage model and a generalized shear–flexure coupled model, is proposed to have a closer insight into the damage transition within the wall–frame structures. The relation between the stiffness ratio and the ratio of vibration periods is established by introducing two stiffness‐based damage indicators and modal damage indexes. By this relation and the stiffness degradation in the frame part and wall part, the correlations between the modal damages, global damage, and the damages of the two parts are clarified. The combination of the damage indicators of the two parts with global damage is proved to be capable of capturing the damage transition during the dynamic redistribution of internal forces. The case study indicates that the damage predictions of the wall–frame structures are consistent with the interstory drift and proportions of failed components. The comparative study implies the efficiency of strengthening the link beams.

钢筋混凝土墙框架结构内地震破坏过渡的宏观方法

迄今为止，提出的破坏模型未能识别出一种典型的双重结构系统（即墙框架结构）在强烈地震下的破坏过渡。从概念上讲，将宏观的全局损坏模型与简化的结构模型结合起来，可以描述结构的框架部分和墙部分之间的相互作用机制，这在概念上是有希望的。因此，提出了一种宏观方法，将宏观整体损伤模型和广义剪切-挠曲耦合模型集成在一起，可以更深入地了解墙框架结构内的损伤过渡。通过引入两个基于刚度的损伤指标和模态损伤指标，建立了刚度比和振动周期比之间的关系。通过这种关系以及框架部分和壁部分中的刚度降低，阐明了模态损伤，整体损伤以及两个部分的损伤之间的关系。这两个部分的损坏指标与整体损坏的组合被证明能够捕获内力动态重新分布期间的损坏过渡。案例研究表明，墙框架结构的损伤预测与层间位移和失效构件的比例一致。对比研究表明加强连接梁的效率。这两个部分的损坏指标与整体损坏的组合被证明能够捕获内力动态重新分布期间的损坏过渡。案例研究表明，墙框架结构的损伤预测与层间位移和失效构件的比例一致。对比研究表明加强连接梁的效率。这两个部分的损坏指标与整体损坏的组合被证明能够捕获内力动态重新分布期间的损坏过渡。案例研究表明，墙框架结构的损伤预测与层间位移和失效构件的比例一致。对比研究表明加强连接梁的效率。
