系统识别问题在结构工程领域变得越来越重要，特别是在评估现有结构的损坏和恶化方面。本文提出了一种基于多元 ARMA 模型、应用卡尔曼滤波器和全局迭代来识别现有结构的固有频率和临界阻尼比的方法。通过将该方法应用于在四层钢筋混凝土建筑物上测量的微震记录来验证该方法。
The problem of system identification has become increasingly important in the area of structural engineering, particularly in connection with the assessment of damage and deterioration of existing structures. In this paper, a method is presented to identify natural frequencies and critical damping ratios of existing structures on the basis of a multivariate ARMA model by appling the Kalman Filter incorporated with a global iteration. The method is verified by appling it to microtremor records which are measured on a four story reinforced concrete building.
