Abstract
Reinforcing concrete connections using superelastic shape memory alloy (SMA) facilitates developing monolithic self-centering earthquake-resistant concrete frames designed to dissipate energy through a flag-shaped hysteretic response. In this research, a new monolithic self-centering concrete beam-column connection was proposed and experimentally validated by testing a large-scale connection under cyclic loading. The connection was detailed to precisely control the center of rotation in the beam member and mitigate damage to slabs attached to the concrete beam. The connection was designed to relocate the center of rotation away from the face of the column based on the newly developed double slotted beam (DSB) technology. The test results were compared with experimental tests of SMA-reinforced single slotted beam-column connection found elsewhere in literature and a control conventional reinforced concrete connection. Test results indicated the ability of the connection to self-center while experiencing a flag-shaped hysteretic response.
