Effect of Configuration and Yield Strength of Transverse Reinforcement on Lateral Confinement of RC Columns

In general, the lateral confinement capacity of RC columns is influenced by strength and configuration transverse reinforcement. this study, performed antisymmetric flexural moment experiments that simulated seismic loads, with yield reinforcement square as main variables. The eight specimens were cross-sections measuring 250 × mm, effect in relation to variables was examined inducing failure plastic hinge zone under a shear span-to-depth ratio (a/D) 3.0. Transverse reinforcements comprised octagonal S-series tie-based H-series. strengths 453 MPa 1053 MPa, respectively. Compared H-series, S-series, whose closer circular form, exhibited more prominent ductile behavior after increasing reinforcement, which indicates greater confinement.
