I have Analysed & Designed attached file of STAAD using Select series 4 & Select Series 6. I am getting different output from both.
Some of the member fails in Series 4 while passes in Series 6. Why so ?
Build number for Select series 4 is 20.07.09.31 and
Build number for Select series 6 is 20.07.11.33
Please solve my querry.
Below attached is STAAD editor file.
