  1. Your suggestion is good and new categories should be made. I think ranking questions interms of difficulty would be hard because a toddler will rank he questions that are hard for him. Do you have a proposal on how to make it happen (interms of forum split). Good suggestion.
  2. You can use section designer to model hollow column and can also create ramps for stairs using the extrude command. I think it is better to keep your model simple and exclude ramps whatsoever.
  3. Yes you can. You can also use Section Designer if the column size is not regular.
  4. It is the same as designing a column with a stair case inside it. Thanks.
  5. Check the tutorials at: https://www.csiamerica.com/products/safe/watch-and-learn
  6. You can let the main beam crack. You know the applied force and you can calculate the stress due to force and subsequent crack width.
  7. I haven't checked your model but here are a number of things to consider. 1. For 1, you can set torsional modifiers zero where you anticipate compatibility torsion. Check the link below: 2. You might want to check your applied load units as well as load combinations. Either, the error is correct or applied load, load combination or section size is incorrect.
  8. See the attachments. It answers your question and explains the fundamentals as well. Inelastic_Seismic_Behavior_Notes.pdf
  9. Generally to keep construction simple, people go with maximum reinfo throughout unless the max reinfo is too big. If that is the case, they use additional bars at critical locations.
  10. No, I have never seen this before.
  11. Details: https://www.amazon.ca/Reinforced-Concrete-Design-Tall-Buildings/dp/143980480X
  12. First analysis tells you how much you structure would displace under gravity load. Second order analysis considers the displacement under gravity and its consequences. In simple words, you are checking a displaced structure under the effect of gravity load.
  13. Can you share the error code or number?
  14. Why do you want to do this?
  15. Can't we apply those forces manually on vertical supporting elements?
