  1. R.c Hibbeler's structural analysis is also worth reading and enjoying 😁
  2. Dear Uzair, I'm also facing the same problem.my building is in zone 2A,soil sd,all spans are less than 25ft,slab thickness 6",size of columns and beams are 12"x30" and 9"x18" respectively. Seismic load cases are 4. End result is all columns are having steel 1%.is it ok to have same %age in all columns? Or something is definitely wrong?
  3. Thnx a lot for ur kind co operation.i ll check it
  4. Wat abt static analysis!! How to get T if performing static analysis.i think go to TABLES, isn't it?
  5. interesting discussion!!! but how can we check T i.t the fundamental time period in ETABS?
  6. interesting discussion!!! but how can we check T i.e the fundamental time period in ETABS?
  7. Kindly elaborate the second point sir,thnx
  8. Aoa dear S.Es Wat is the criteria for selection of a particular type of a foundation especially with reference to an RCC building? e.g A RAFT or SINGLE FOOTING?
  9. Dear Baz, From your discussion,wat i hv been able to conclude is that a column will b designed as a Short column(neglecting p-delta)or Long column(including p-delta.is it so,sir?
  10. Aoa respected SEs.it has been learnt that p-delta effects are considered under certain conditions.it is not necessary to consider it in every project.wat are the conditions? When to include it n when not? Elaborative comments will be highly welcome.thnx n regards
  11. THNX for reply sir it wud b convenient for me if u write down step by step procedure for adding load combos.can u plz write down step by step procedure for adding load combos,i also hv seen ur ETABS CHECKLIST but still im unable to understand.hope u understand my point.looking for ur expert comments.
  12. Dear experienced fellows, a comprehensive material on load combos is required,entailing a complete philosophy of load combos DCON1,2,3,4 etc n UDCON 1,2,3 Etc.wat is difference between these n wat is correct procedure of using combos in Etabs ver 9?is it adding all default combos or are there separate combos for STATIC and DYNAMIC ANALYSIS? Wat is enveloping of combos n how it it done.wat is difference between service n ultimate design combos?does this mean strength design or allowable stress design combos? In books i hv read only basic load combos i.e LRFD(Strength design) and ASD thn how to make derived combos from that basic combo.In a nutshell wat steps shud we follow if we r designing a model using STATIC Analysis.thnx n regards
  13. Aoa restored S.Es. in an eight Story building, in lower stories columns, area of steel ranges from 2-7%,c column size 12x30 beams9x24.As in columns is too high.shud I increse width of lower columns or provide shear walls? Secondly if Shear walls r to b used then these shud b provided along periphery of basement or provide all along the overall height of the building? Which option is economical I.e columns area or shear walls? THNX n regards
  14. In an eight story building basement+ ground+7,Sd,2A. Columns reinforcement in base,ground and 1st is as high as UpTo 7℅.columns size is 12x30 n beams 9x24. I hv two options either to increase columns width in lower stories or to hv Shear walls.Are shear walls to be provided in basement only or to increase UpTo the overall height of the building? Which of the two options will be economical? Thanks n Regards
  15. THNX Umar. Always looking for ur fairly informative attachments in future too.
