I design a very simple column to verify the concrete column design using ACI-08.
Column Size : 250 mm x 250 mm
Bar arrangement : 4-D20, (D12 @ 250 mm for tie)
However, P-bal and M-bal in Analysis output are not same with manual calculation.
Please help me to verify below design result.
The cover depth is 30mm.
Please attach the related model and your hand calculations.
