RE: SDC D Ordinary Moment frame connection using HSS sections

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I wouldn’t say it was impossible it just has to be from one side, using backing plates: which may still be the preferred practice if using wide flange beams especially if they lack depth. The Seismic requirements I cannot comment on.

Subject: SDC D Ordinary Moment frame connection using HSS sections

 

Can HSS sections be used in an Ordinary Moment Frame in a SDC D.  I can’t see, in the seismic design manual,  where it is specifically excluded, but I can’t find any information for the HSS Beam to HSS column connection design.  It seems that it can’t be done since a full pen weld is difficult if not impossible to do for a HSS beam to HSS Column face.  If there is an example out there I would love to see it.  I am doing some work for a fabricator and they are expecting HSS sections due to what is seen in the construction documents.  I have to let him know real soon if he will need to go to wide flange members.

 

Thanks for the help,

Joe Grill
