摘　　要：应用有限元方法 ,建立结构柔度矩阵 ,在柔度阵法识别结构损伤的基础上 ,构造损伤识别的二次规划模型 ,提出了一种悬臂弯剪型建筑结构的损伤识别方法。通过一个悬臂弯剪型结构损伤识别的数值模拟表明 ,只需低阶模态参数就可有效地识别结构损伤。The finite element method is used to form a flexibility matrix of a structure.Based on the structural damage identification by the flexibility matrix method a quadratic programming model is made;and the damage identification method for a cantilever flexible shear building structure is suggested.It is indicated by a numerical simulation of the cantilever flexible shear structural damage identification that only low order modal parameters are needed to identify effectively a structural damage.
