The challenge for this task rose from the fact that the identified modal characteristics were not adequate for the use of one of the advanced automated model updating methods that are available. In particular, the only usable parameters that were identified were some natural frequencies and their corresponding mode types but not eigenvectors. Safely assuming modern building conditions, the absence of localized structural damage and the linear behavior during the identification measurements, an empirical manual updating procedure is implemented for updating standard key parameters of the FE model. During the updating procedure the identified quantities are used to define the models uncertain parameters such as moduli of elasticity and boundary conditions, whilst robust engineering reasoning is implemented for the best and safest exploitation of the available identified modal data.
