RE: Steel SMF

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I believe that none of the prequalified moment frame connections have 
considerations for weak-axis columns, at least not in AISC 358-05 
(Prequalified SMF/IMF).  Have you considered creating a strong-axis column 
section?  There are provisions in AISC 358 to create a "Flanged Cruciform" 
Column.  That is cutting another W flange section in half and welding it on 
 either side of your corner column, forming a cruciform-shape column.  Lots 
 of welding, though.

Good luck

Good afternoon,

Can somebody share a good reference (if any) regarding the design of a 
steel SMF with beam framing along the weak axis of the column (it's a 
corner condition, beams in both directions)?

I got FEMA 355D, and it helps - but, for the sake of plan checking, would 
appreciate something more recent, at least post-Northridge.  In this sense, 
 the 2009 NEHRP/NIST Technical Brief 2 Section 3.5.3 is quite
