%X Based on the theory of structural dynamics,the damage identification and diagnosis of existing steel truss bridges is studied.With the natural frequency as the characteristic parameter and using method of BP neural network and the MATLAB,the damage identification and diagnosis is analysed and a complete flow chart for the bridge damage identification and diagnose is proposed.With the method,the damage process of a steel truss bridge is numerically stimulated.
