Hi All,
Is it possible in STAAD Pro. to design a steel composite beam with positive moment as what may happen on continuous span? I got a warning when checking a beam that my beam has positive moment which have not designed for.
Is there any solution for this?
Thank you
As of now, STAAD.Pro can handle positive moments in the design of composite beams for code check as per the AISC 9th edition code only ( CODE AISC ). For that code, if the critical section is at a location that has the concrete in tension, it designs the section as a non composite section. For the LRFD 3rd edition implementation ( CODE LRFD ), the software ignores the positive moments while carrying out the composite beam design and prints a warning message, as you mentioned.

Hi Sye,
Thank you for your usual replies and guidance.
I was wondering if this issue has been resolved? I can see the question was in 2014 and I'm facing this issue till now. Please advise if there is a recent LRFD code that design positive moment along with the composite section.
One more point I also find odd in the composite design in staad, When I apply composite deck slab, it only defines the beams prependicular to the rid as composite , what about the beams parallel to the rib, why do we have to define as composite manual? or am I missing something? Thank you in avdance.
