Casey,
Footnote h to Table 12.2-1 refers to section 12.2.5.6 & 12.2.5.7 where both OMF and ISMF are permitted if the requirements are met. It even mentions that OMFs are allowed in the footnote h.

Joe:
No. OSMF is not permitted, period.
This is not because of HSS sections.
You may refer to Table 12.2-1; item C4.
OSMF is only permitted in SDC A, B & C.
In SDC D one can only go with SMRF or if qualifies for footnote "h", may use ISMF.

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
