Updating of Finite Element Model in Considering Mode Errors with Fuzzy Theory

Finite element model updating aims at reconciling the analytical model with the test one,to acquire a refined model with high-fidelity in structural dynamic properties.However,testing data are inevitable polluted by noises.In this study,the mode parameters and design variables are modeled as fuzzy variables,and a fuzzy model updating method is developed.Instead of a single optimal model,a set of satisfactory models is obtained.The most physically compatible solution is sorted by insights to the structures.The proposed method is applied to a real concrete bridge,for which a physically meaningful model is identified.
