本文将高层建筑、烟囱等高柔结构当作弯剪型悬臂结构，提出了一种利用结构动力模态数据识别结构损伤的柔度方法。本文方法的特点是所需模态阶数少，便于实际应用。算例和试验分析表明，本文方法是可行的。
In this paper, high-rise buildings, chimneys and other high-flexible structures are used as bending and shearing cantilever structures. A flexibility method for identifying structural damage using structural dynamic modal data is proposed. The characteristic of this method is that the required modal order is small, which is convenient for practical application. Examples and experimental analysis show that this method is feasible.
