ETABS Ultimate C 21.0.0 Beam Design using ACI-318-14

[Er.Shinu]

In RCC Beam design using ETABS version 21.0.0 using ACI 318-14 code, the results displayed and PDF design calculation from ETABS is showing mismatch. Can anyone help how the Ast 934 mm2 is obtained?

Check if the difference is due to torsion. The beam will see torsional load as it sit on the edge (slab moment will act as torsion on the beam). You can see the torsion reinforcement separately from >> Concrete Design >> Beam design.

Yes that is my question. The beam has torsional moment. The flexural longitudinal reinforcement is 642mm2. The torsional longitudinal reinforcement is 766mm2 (for top and bottom combined). But the total longitudinal reinforcement displayed is 934mm2. How the value 934 is arrived. Is it software error or any surprising calculation is there behind. I don't know. No body know. Please see the attached screen shots sir.
