Massachusetts Building Code R=3
Massachusetts Building Code R=3
(OP)
This question is for anybody that is familiar with the massachusetts state building code. It does not appear that the current edition allows you to take R=3 for steel design of buildings. So you would need to design and detail all buildings to meet AISC seismic requirements even if they fall into design category C. Is this correct, am I missing something? Thanks.

I would have a hard time believing that is accurate.

This is where a debate can occur if you would like to mix and match code (use a newer version of the 92 seismic provisions of which some stuff doesn't make sense). I know people advise against doing this.
From what I have heard the new 7th of the building code is still a few months away and does not update the steel code to the 13th edition (still using the ASD 89 spec).
RE: Massachusetts Building Code R=3
I would think that with all of the newer research being done in the new seismic manual, that would substantiate an R=3 (using the same limitations), but you may want to check to see if your jurisdiction will allow it.

I was told at a seminar that R=3 was just an arbitrary number and was not back by test data.

It appears they will let you use an R=3 in the new code with height limitations SDC B = 100 feet and SDC C = 65 feet. Hope this helps (and the link works)
