AOA every1 my query is that while using SET ANALYSIS OPTION then in P-DELTA check which option shud b checked i.e ITERATIVE or NON-ITERATIVE? wat is th difference and under wat conditions .ALSO explain to me that we use p-delta analysis when stability co-efficient is not satisfied after determining seismic parameters so how can we check the p-delta option before running analysis.thirdly wat is the criteria of checking the DYNAMIC ANALYSIS TAB? Also in seismic design there r two procedures 1- STATIC 2-DYNAMIC which one to be used n under wat conditions.does it have any connection with the overall height of the structure? lastly y we still use UBC-97 whereas it has been replaced by I.B.C ?.
