UPDATING THE FINITE ELEMENT MODEL OF LARGE-SCALED STRUCTURES USING COMPONENT MODE SYNTHESIS TECHNIQUE
It is difficult to update the finite element (FE) model of the large-scale or complex structures such as bridges by using the regular methods since the dynamic analysis of complex structures always result in the heavy computational burden. A new updating method based on component mode synthesis (CMS) was proposed to improve the efficiency of FE model updating of large-scale structures. The effectiveness of the proposed method was validated by updating the FE model of a scaled bridge model with measured modal parameters.
