*warning* Member# 1 is not a valid Aluminium Section.
And so on for all members
0 errors , 90+ warnings of this type..... No Design result of Aluminium due to warnings of this type
Sir help here, what to do now after these warnings
At this point, STAAD.Pro can only design aluminum sections assigned from the Aluminum property tables supplied with STAAD. The warnings that you are getting is indicating this as user defined sections can't be designed.
