Studies of Joint Damage Identification for Frame Structures
In this paper, Improved back-propagation neural networks (shorted for improved BPNN) in which combined parameters are chosen as input vecter is used to identify joint damages of steel frame structures. Forthermore, the noise injection training techniche is introduced to enhance the anti- interference capability of the neural networks. It has proved that the proposed mothed was a good selection to joint damages for frame structures through numeral verification on a four-story frame and experimental verification on a tow-story frame.
