Composite Concrete Coupling Beams with Embedded Steel Plates
Benefits of the proposed system, consisting of reinforced concrete beams with embedded steel plates, include reduced congestion relative to diagonally-reinforced concrete coupling beams; reduced interference with wall vertical steel relative to coupling beams with embedded structural steel sections, and improved constructability relative to both diagonally-reinforced and structural steel-reinforced coupling beams. This research project will involve large-scale testing of composite coupling beams with embedded steel plates to assess performance, providing essential data to describe the behavior, modeling, and detailing requirements for coupling beams with embedded steel plates subjected to reversed cyclic loading. Test results will be synthesized and presented to ACI/ASCE/AISC committees in the form of a code change proposal and a final research report.
