【Abstract】 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.更多还原
