摘要: This paper introduces a frequency-domain method of structural damage identification. It is formulated in general form from the dynamic stiffness equation motion for structure and then applied to beam structure. Only matrix intact state appears final identification algorithm as model. The appealing features present are: (1) it requires only frequency response functions experimentally measured damaged input data, (2) can locate quantify many local damages at same time. feasibility tested through some numerically simulated analyses experimental verification conducted cantilevered with caused by introducing three slots.
