Abstract
Model updating is a common method to improve the correlation between finite element (F.E.) models and measured data. F.E. model updating is a technique that is used to identify and correct uncertain modelling parameters that leads to better predictions of the dynamic behavior of a target structure. A number of approaches to the problem exist, based on the type of parameters that are updated and the measured data that is used. This paper concentrates on an updating method based on measured modal data. The conventional F.E. updating techniques are extended and adapted in order to take into account the uncertainty on the estimated modal parameters to be updated. The effectiveness of the suggested procedure is tested on a case study.
