Table 1: Relevant values of the designed connection. The test specimen was mounted on two supports that were installed at each end of the column. Support 1 is shown in Figure 4a, and it was restricted for translations in the plane and out of the plane. The support 2 is shown in Figure 4b. This support was restricted for vertical translation and out-of-plane translation. Rotation in the plane was allowed at both ends. The restriction of the translations was achieved by means of plates connected to the lower base of the MaPH, while rotation was allowed by means of a pin-type connection. The test specimen was assembled in a T-shape, as shown in Figure 3. In this configuration, the column was positioned horizontally and the beam vertically because the displacement system driven by the hydraulic actuator was located on top of the frame. The actuator allowed a maximum level of cyclic displacement of 270 mm. The deformed position of the frame at its maximum displacement during a displacement cycle can be observed in Figure 5.  
Figure 4: Supports utilized in the assembly: (**a**) Support restricted for translations in the plane and out-of-plane; and (**b**) support restricted for vertical translation and out-of-plane translation. Figure 3: Experimental setup, including the mounting details of the beam-column connection: (**a**) Two supports were installed at each end of the column having the following constrain conditions: at end 1, translations in the plane and out of the plane were restricted; at end 2, vertical translation and translation outside the plane were also restricted; rotation in the plane was allowed for both ends; and (**b**) beams that provide lateral support to the framework.
