  2. sir first of all thnks for replying in that much detail. and yes i have started this so inshALLAH it will keep this going. and i am in my final year 7th smstr. i am also doing this manually and i want to compare it with etabs for that reason i am doing it in etabs but i can compare it when i will do it correctly in etabs so thats why i shared it here so that i came to know how to do it correctly as if i dont do it correclty then results will not match. u pointed alot of things and i have started working on it but its really very difficult after reading about different thing here on SEFP i came to know that i knows nothing about structurl engrg its very tought.. one of our teacher taught us about this so i did it in that way plus other help taken from differnt soucres and i am combining that all so thats why there r mistakes about applying modifiers, assigng slab as shell etc . sir i have noted these all and also doing it manually nd will return back after that with more questions thnks again 4 ur time

  4. some more comments:- dont apply raft in your etabs model..export the reactions to SAFE and model raft there...or if you want to model it in etabs..then dont apply fixed supports..apply area springs according to your soil properties...in your model i have removed the raft... you applied PLATE option for RAFT..but you should be familiar with the differences between MEMBRANE, PLATE and SHELL... This time i have applied modifiers according to your approach...( inside frame section properties..) now you should not select the beams or cols and goto ASSING>FRAME>MODIFIERS...dont apply it again..otherwise it will be duplicated and etabs will multiply both values...i mean if you applied inside 0.25 and then from menu again 0.25 so it will consider 0.25x0.25 remember i have changed your slabs to MEMBRANE..so no need to apply meshing to MEMBRANE...also before designing your sections select sway ordinary as in your case the frame is not sway frame... still i didnt applied manual checks..you should do it your self...calculate the tributary area of any column and multiply by load..and see if your base reaction for that column is okay or not? check the loading of a beam manually and compare with etabs... calculate the moments of any frame on a grid by ACI 8.3 approx coefficients method and compare...or you can moment redistribution methid,,, now u must be thinking how hard struc engg...makes the life... my version is 9.7.4 so im attaching only text file..import it in your etabs model... good luck assignment_checked.zip
