Abstract: Finite element simulation serves as a key role in dealing with complex structural problems. The uncertainties existing in structures, test data and computational models，usually impede to verify and update a FE model, and to obtain a validate model with prediction confidence. A framework of FE model validat ion is proposed here to attempt to illustrate the essential ideas and feasibility of the model validation.
Keywords: finite element method, model validation, model updating, uncertai nty quantification, principle component decomposition.
