Effect of Axial Restraint on the Seismic Behaviour of Shear-Dominated Coupling Beams: Reinforced concrete coupled walls are an efficient structural system for medium to tall buildings which provides large stiffness and strength against wind and seismic loads. The coupling of the individual wall units is typically provided by short and stiff coupling beams which deflect in double curvature with high shear stresses, and therefore are susceptible to brittle shear failures. At the same time, in regions of high seismicity, the coupling beams are required to possess large ductility and

It involves near-full-scale (1:1.5) two-bay 2D frames with three stories in order to include a typical intermediate story (the middle one), the ground story with the connection to the foundation, and the top story with the column bars terminating at the level of the roof. The 2D frames are involved in one-way frame action, due
...more Hybrid Testing of an Existing Steel Frame with Infills under Multiple Earthquakes: Seismic performance of a multi-storey steel moment resisting frame (MRF), that was surveyed in the recent 2016 earthquake sequences in Central Italy, was investigated through pseudo-dynamic hybrid simulations. The seismic performance of the reference structure was evaluated by testing a 2/3 scaled model of a sub-structure. The structure was tested under the series of strong motions recorded during the 2016-2017 Central Italy earthquakes. In the next phase, a two-storey one bay sub-assemblage steel
