| Abstract: | The problem of structural damage identification can be converted to an optimization solution of the objective function with constraint in mathematics. The adaptive immune genetic algorithm, which was pro posed based on the optimization mechanism of chaotic system and the basic mechanism of immune system, is employed to identify the structural damage. The efficacy and feasibility of this method is studied in this paper. Numerical results of the element damage identification to the plane framed structure example demonstrate that this method is practical and feasible. |
