Kurzfassung
The updating technique aims for the reconciliation of analytical structural models with static and dynamic test data. A finite element model which produces correct static and dynamic deformations and normal frequencies is expected as the result of this updating process. Therefore, the finite elements that contribute to the discrepancies between the analysis and test have to be identified. The kinetic and potential energy distribution in combination with thecondition number of the updating equations is proposed as a powerful and reliable criterion to solve the task.
