Two full-scale building structures have been tested pseudo-dynamically in the ELSA laboratory, namely a 3-storey one-bay steel moment resisting frame and a 4-storey R/C building. Design of these structures was performed in accordance with the relevant Eurocodes. In particular, some design solutions that could lead to a semi-rigid joint behaviour were to be investigated. The behaviour of the tested structures is discussed, focusing mainly on the influence of the semi-rigid beam to column joints on their seismic performance. The steel frame performed well; however due to excessive deformations in the connection zones the welds collapsed before the full exploitation of the potential beam ductility. The R/C building also performed well during the test; however slippage of the rebars (B500 steel) in the joint core occurred, leading to an excessive decrease of the structural stiffness and reducing the energy dissipation during the earthquake.
