Beam and column design fails in ductile detailing but is ok in non-ductile in RCDC? Why ? And how do I get ductile detailing of beams columns without increasing cross section?

In ductile beam design - generally beams are failed due to sway shear. it is only applicable to Ductile beam only. The sway calculation is based on provided reinforcement in beam. if the sway shear is high and section is failed due to shear, there is only option to increase concrete grade OR section size. for column design - generally column fails in Joint check. it is also depending on the provided reinforcement in beam and column. if any column failed in joint check, it can be pass with increasing concrete grade OR column size. you cannot compare design of Non ductile beam and column with Ductile beam and columns. Please go through the design and detailing clauses of ductile code for more information.
