Good day,
Can STAAD pro be used to account for the additional stiffness and strength provide to steel columns from the concrete encasement (composite column sections)? I have noticed the fire protection tab in specifications and I've read in Article 5.20.9 of the Help Contents that STAAD pro does the weight calculation of these members through the use of the self weight command, but no mention is made of the strength effects this encasement will have on the structure.
Regards
