In 2013, Indonesia published new reinforced concrete (RC) design code (SNI 2847 2013) . This code improved the previous reinforced concrete design standard.
This standard also specified detailing for RC buildings in the high-risk earthquake region.
At columns of special moment resisting frame, transverse reinforcement is needed to
allow column to have large deformation demand without degradation in lateral load
resistance. In this study, the confinement design equation SNI 2847 2013  are
evaluated with columns test data with several parameters. The result of study showed that
the confinement design equations are needed to improve.
