2.3. Testing protocol and setup The experimental setup for the in-plane cyclic tests took advantage of the three-dimensional strong-walls/strong floor configuration of the EUCENTRE laboratory (Magenes et al., 2010; Senaldi et al., 2018). Three servo-hydraulic actuators, with a maximum force capacity of 500 kN each and a stroke of 0.76 m, were connected to a steel beam fastened to the RC spreader beam. Two actuators applied an axial load to the specimen, while the third one imposed horizontal displacement to the top RC beam in the North-South direction (Fig. 3).
