提出将结构损伤的物理参数辨识问题转化为识别损伤位置和损伤程度的优化问题,利用结构时程响应的唯一性,通过预测结构模型与实际损伤结构构建目标函数,采用QPSO算法全局优化定位定量进行结构损伤识别,最后通过六层框架的数值模拟验证该方法的有效性。
The problem of identifying physical parameters of structural damage is transformed into the optimization problem of identifying damage location and damage degree. The uniqueness of structural time-history response is used to construct the objective function by predicting the structural model and the actual damage structure. The QPSO algorithm is used to optimize the localization and quantification Structural damage identification, and finally verify the effectiveness of the method through six-layer numerical simulation.
