Reinforced concrete coupling beams, often used with special structural walls, have a large deformation capacity if detailed in accordance with ACI 318-14. These beams are typically difficult to construct due to congestion of the reinforcement, which can limit their design strength. Verification of the performance of coupling beams with HSS used as diagonal, longitudinal, and transverse reinforcement could allow for greater nominal shear and flexural strengths for given beam dimensions.
