I am trying to design HSS beam to HSS column moment connection. Is there any resource for that. if i will use weld all around is this consider as moment connection.
Supplement 1 for AISC 358-10 has a pre-qualified HSS column moment connection. However, it connects to wide flange beams.
AISC chapter K (and the commentary) has lots of criteria related to HSS to HSS connections. I don't think any of them would qualify for seismic moment frames. But, it does look like some of them would qualify as moment connections of some sort.
Modes of failure and design producers of HSS to HSS/CHS is completely different ,you have to check punching shear failure and web side failure ,AISC has got design guide lines for these
