The use of short-grouted ductile rebar connectors would significantly simplify the construction of precast wall and frame structures; however, existing Type II grouted connectors do not have the ductility capacity to develop the high cyclic rebar strain demands at yielding joints. This research project will address this market need using a non-proprietary and cost-effective, high-performance, yet simple, grouted connector using available corrugated steel ducts and grout products. This research will conduct the required ACI ITG 5.1 and ITG 1.1 validation testing of precast wall and frame structures using the proposed connectors in high seismic regions. The specific structural systems to be validated and related test specimens will include Special Shear Walls, Rocking Shear Walls, and Special Moment Resisting Frame Columns.
