Why does a reduced beam section (dogbone cut) in steel SMRF frames intentionally shift yielding away from the column face?

Choices

• (A) It arbitrarily boosts joint strength without planning hinge zones
• (B) It concentrates ductility in a calibrated beam segment per prequalified connection provisions
• (C) It denies column shear participation in lateral systems
• (D) It only amplifies footing plastic demand
