This paper proposes an approach to identify complex parameters describing concrete creep degree based on the simulated annealing (SA) principle.Through the existing engineering examples,the technique for variable perturbation is used to validate the astringency and credibility of the SA algorithm,and the sensitivity ofinvolved parameters to the objective function of the SA algorithm is also analyzed.Further,this study verifies the merits of the approach in simple programming structure,good stability,high calculation rate and accuracy.The SA algorithm should be recommended to apply for the multi-parameters identification of the similar engineering issues.
