  1. 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.
  2. No, I have never seen this before.
  3. Details: https://www.amazon.ca/Reinforced-Concrete-Design-Tall-Buildings/dp/143980480X
  4. 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.
  5. Can you share the error code or number?
  6. Why do you want to do this?
  7. Can't we apply those forces manually on vertical supporting elements?
  8. How is that possible?
  9. You can find time period for seismic analysis done through Equivalent Lateral Force procedure by printing the summary sheet.
  10. Please post.
  11. Where are the the research details that show 10% marble powder strength increase?
  12. ETABS has a built in detailing feature. https://www.csiamerica.com/products/etabs/features Here are a few others. https://www.s-cube.in/ProductRCDC.aspx http://www.farasaeg.ir/etabsmate_en.htm http://zaxises.com/rcbeamdetailer.htm I have personally tried none of these so can't give you any expert advise about specific softwares.
  13. Valid points but any requirements for shear and moment demand should be met by "increasing the thickness of foundation" rather than relying on a beam to do so. The reason being that foundation (in this case strip foundation) reinforcement and formwork requirements are very simple and less labour intensive. Introducing a beam would make it complicated and more costly and in some cases an overkill. Also beam foundation will have no significant affect on settlement as I believe settlement is a function foundation width and bearing pressure, which in both cases would be similar.
  14. Differential settlement consideration for tie-beam is a good design practice. Good point.
  15. I can't see any difference.
