Resumen
Proper designed of transverse reinforcement in RC column is needed to maintain its ability to deform under axial and shear load safely. Even though mandatory building codes for transverse reinforcement of RC column exist, shear failure was still found in the last high earthquake in Pidie, Aceh in 2016. Therefore, as an attempt to improve RC column strength and ductility, the effect of transverse reinforcement configuration was evaluated experimentally to a column subjected to an axial and shear load. Four scaled columns were fabricated to simulate an actual structural member with a cross section 200 x 200 mm. Four types of transverse reinforcement configuration were applied in each column. The test was carried out by loading an axial load constantly and shear load gradually until its failure. The test results show that the configuration of transverse reinforcement has a significant effect of maintaining column stiffness, which was subjected to compressive axial load and shear load. Furthermore, the configuration of transverse reinforcement influences the compressive strength significantly and enhance the concrete shear capacity of a column due to its confinement effect.
