The damage identification is made by the numerical simulation analysis of a five-storey-and-two-span RC frame structure,using improved and unimproved direct analytical method respectively;and the fundamental equations were solved by the minimal least square method(viz.general inverse method).It demonstrates that the feasibility and the accuracy of the present approach were impoved significandy,compared with the result of unimproved damage identification.
