In AS3600 - 2018 wall section, one condition we can avoid using confinement as columns (when design wall as column) is when vertical reo ratio is <= 0.01. But how can we achieve this when we design wall as column in the first place?
Also, what does "the vertical reo is not used as compressive reo" mean? Does that mean when we design the wall using P-M iteration we don't including the contribution of steel in compressive zone? Otherwise I dont get how we can avoid vertical reo in compression especially during an earthquake event when concrete cracks and the reo in compression zone will tend to buckle without the use of confinement?
