How many of you have designed composite beams on ETABS? I tried to design but it differ from manual calculations. Moreover for the same model AISC LRFD 99 doesnot give the result but 94 gave... Some of our friends also experienced same problem...
Please share your experience and tips if any..
Regards
Dear friend, I dont really trust in the module of etabs for composite beams. The results differ from manual calculations in the perimetral beam, i believe the problem is with the effective width.
Also i use other equation to calculate vibration.
