Hi,
I tried running staad pro for simple concrete modeling, with using code of ACI 2014. I've only put dead load and live load for analysis, in output file i found an error in all column design.
| Criteria: |
| 1.10.7.6.1.2 |
| Error : |
| 1.An analysis result contains a minimum limit that is greater |
| than the maximum limit |
but when I tried to change the code to 2011, the error did not appear. Can someone tell me why this error showed up for ACI 2014 code?
