Dynamic Condensation Approach to Finite Element Model Updating

Weng, Shun / Zhu, Hongping / Xia, Yong

In Chaps. 10 and 11, the IOR method are proposed to compute the eigensolutions, eigensensitivities, structural responses, and response sensitivities. This chapter extends the IOR method to the sensitivity-based FE model updating using modal data (eigensolutions) and time history data (structural responses). The eigensolutions or structural responses are calculated using the IOR method to construct the objective function. The eigensensitivities or response sensitivities are then computed for each design parameter to serve as a search direction in model updating.
