An error is showing during the verify all members passed in SAP2000 for a G+3 RC Hill building. The bottom columns of dimension 400x400 mm2 while remaining columns dimension is 300x300 mm2. The percentage of steel is also reached in its max value i.e. 6% as per IS 456:2000. But it shows the capacity failure in the longest columns at ground floors while others have been passed.
In this I am unable to think about how to these three columns will be passed without violating IS 456: 2000 and other irregularity in the models.
May you suggest me as how can I remove further this failure?
