Hello again.
I was adding some user shear reinforcement to a model recently (hurray for this being a feature now), and had some things happened that piqued my interest. I started digging around in the audit report to better understand how Concept is calculating the required shear reinforcement. So far, I have everything worked out except for the 'Available Vn'. I cannot seem to resolve how this value is being calculated. I have a feeling it still has to do with Eqn 11-18, but have not been able to quite work out what is being used for that value.
Also, in the attached model and auditor screen shot, you can see that the calculated value for 'Minimum additional design Av/s' (0.03765 per ACI eqn 11-23) is greater than the Av/s calculated for torsion (0.03337). However, the final design Av/s used is the (shear Av/s) + (the torsion Av/s), which is less than the (shear Av/s) + (minimum torsion Av/s). Is this done for a certain reason?
Finally, on a totally unrelated note, I was hoping that I could get some assistance in the forum with this post:
Is there a working version of the spreadsheet mentioned in this post that could be shared before the examples in that post are finalized? Having the ability to use tabular input in Concept will be extremely helpful for a project that I have coming up in the near future. If the VBA spreadsheet isn't near completion yet, would it be possible for one of you to send me a GCFF example file that I could use to begin making my own version of this spreadsheet (not really interested in converting STAAD to Concept...more in creating input files from scratch and importing to concept). If you could send me a GCFF file that represents the attached Concept model...I feel like that would be more than enough for me to get moving with this tool on my own.
Thanks for the help
Phil
