摘要：

This paper proposed a new method to update the finite element model by using hierarchy strategy and evolutionary computation. The design variables were set to two uncoupled sub-spaces, i. e. node space and section space, and were optimized by evolutionary computation. As an example, the parametric finite element model of a tower crane was constructed, and updated according to its wind-induced vibration results. The results suggest that the proposed method is effective and efficient. ©, 2015, Science Press. All right reserved.
