This is my first time posting here , hope you can help.
Regarding the model attached , please clarify the following questions:
1) When using ACI-11 as the design code we are getting illogical results for shear reinforcement for beams as its varying from span to span although the shear values are close.
2) When changing the used design code to ACI-14 results changes radically as torsion reinforcement required becomes zero while shear reinforcement required becomes consistent on all beams.
Please find model attached for your reference.
