Abstract：Based on the genetic algorithm, the parameter identification procedure was established to estimate the structure vibration parameters and dynamic load parameters according to the observing data of the structure dynamic responses under the action of dynamic load. The computational results testify that the parameter identification algorithm based on the genetic algorithm has better ability to resist measurement noises, and the relative error of estimated results is less than 10% even if the relative error of measurement of dynamic response is 15%. The identification precision can satisfy the engineering demand.
