I'd like to add here that ACI report on punching; in examples, use bi axial moments but they are shifted from column center to centroid of critical punching perimeter (in this way, they are reduced in magnitude). However in PCA Notes (in main chapter of punching) they mention not to take biaxial moment at the same time. Another issue; in PCA Notes (in one of the edge columns punching example), they just take Axial force to check the extent of parameter upto where punching reinforcement can be terminated. They don't use Axial+Moment, they use only axial force for this.
