A Method of Structure Damage Identification for Shear Buildings

摘要

Based on the easy testability and high measure precision of structural frequency, a damage identification method for shear buildings is presented. With frequency being regarded as the function of damage parameters, the homogeneous linear equations with damage parameters as unknowns can be constructed via Taylor expansion. The equations are solved to locate the whole damage location and quantify the severity of the damage. The data used in the method include frequency and mode shape measurement before and after damage. A numerical simulation example using a three-storey sheer structure is given to validate the present method.
