摘要
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。
Flexible structures such as tall buildings and chimneys can be regarded as cantilevers withbending and shear deformation. A deflection approach for damage identification of cantilev-er-type structures by using the vibration modes is proposed in this paper. An important ad-vantage of the approach is that the number of modes required is small, so it is easy for practi-cal application. The effectiveness of the approach is verified by numerical and experimental ex-amples .
