| Abstract | ||||
| The slotted RC beam-column connection was introduced as a promising low-damage beamcolumn connection substitute for conventional design. It consists of a conventional RC beam, modified with a narrow vertical slot adjacent to the column face, running approximately threequarters of the beam depth. In this study, quasi-static cyclic experimental tests were performed on in-plan conventional RC beam-column subassembly RCB and slotted RC beam-column subassembly SL to compare the response of slotted-beams with the conventional monolithic beam and verify the reduction in damage to the connection . The experimental program has demonstrated that the reinforced concrete slotted beam-column subassembly is a viable substitution for the monolithic detail. Extremely promising structural performance was observed. High energy dissipation and stable response were observed to 3.5% beam drift. The system displayed reduced levels of damage to the plastic hinge zone when compared to conventional monolithic subassembly. Beam elongation for the slotted beam was shown to be significantly less than traditional reinforced concrete beams. | ||||
