Work Package 3
In WP3 global numerical models of the pilot buildings will be developed. Preliminary numerical investigations will be performed using
the finite element method (FEM). Geometric and material non-linear behaviour will be taken into account.
These simulations will provide reasonable predictions of the expected maximum loads for the shaking table and hybrid tests.
The previous models will be calibrated on the response of the 3D frames tested within WP4. Geometrical and material properties of the test frames and the devices will correspond to the values which were experimentally determined. Proper modifications of the models will be carried out, as necessary, concerning the member, connection and device properties, in order to achieve a good agreement between analysis and test results.
The calibrated numerical models will be used to study the response of multi-storey frames with DRDs. Case studies designed in WP1 will be numerically analysed. Moreover, the aforementioned building behaviour will be reproduced with simplified yet accurate models to be used during hybrid simulation. The influence of individual parameters on the response of the building will be investigated. Seismic zones corresponding to European earthquake intensity conditions will be considered and characteristic seismic records form real strong motions will be selected. Records will be scaled adequately to obtain the global ductility and the dissipation characteristics of the building frames with and without DRDs.
