  • An experimental study is carried out to investigate a proposed coupling beam: orthogonally reinforced concrete coupling beams confined by steel plates. A total of three specimens were subjected to lateral displacement reversals. Test parameters include: (1) reinforcement detailing, and (2) specimen aspect ratio (ln/h). Some key test results of two coupling beam specimens with diagonal reinforcement layout satisfying ACI 318-14 conducted by Tzeng (2018) is also mentioned, so as to compare the behavior of the proposed coupling beam to the coupling beam required by the current code. Test results indicate that the confinement provided by steel plates could significantly improve both strength and deformation capacity of orthogonally reinforced concrete coupling beam. Furthermore, with the same number and area of reinforcing bars and specimen aspect ratio, the proposed coupling beam exhibited better deformation capability to sustain the force bearing capacity up to 2.1–3.4% higher ultimate chord rotation (du) compared to the diagonally reinforced specimens, while the peak strength (Vpeak) could also be reasonably predicted by the shear corresponding development of nominal moment capacity (VMn).
