Abstract：because of the complicated engineering structures using finite element models are more uncertain parameters and uncertain parameters varied greatly, its slow convergence when the target parameters are updated. for this issue, introducing the hierarchical model of thinking, the complex characteristics of engineering structures by connecting decomposed into several sub-structure, then the sturcture is divided into several sub-parts, respectively, parts, sub-structure of the updating;. finally do not neet to modify the overall structure of an acceptable project generated finite element model, through the model validation techniques in the field of stratified amendment benchmark. the results show that thinking based on hierarchical finite element model updating method has high precision, with great engineering value.
