A detailed Powerpoint presentation of the pseudo-dynamic testing of prototype reinforced concrete 5-story structure designed following ACI-318-02 and NEHRP recommendations for seismic regions carried out on the earthquake simulator-shake table at UC Berkeley. Test structure is a ¾-scale of the first story with column axial load (concentric post-tensioning) simulating upper floors gravity load and unreinforced masonry (URM) infill wall of clay bricks and type N mortar in one of the interior frames. Testing confirmed that URM infill wall significantly changed the demands and the key global and local response parameters, e.g. drift ratio, base shear and joint rotations, of the structure. These experimental findings represent benchmark dynamic test data to validate newly developed on-line testing with hybrid control and sub-structuring and allow the development of new URM infill wall computational models.
