Re: Moment Frame Question

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I don't like it, unless you are limited in some way.
For moment frames in high seismic regions, you really want your column to maintain strength in the event, and your beam to fail first.
The equations for maintaining this are something like Sum (Mnc) >= 6/5 * Sum (Mnb), using overstrengths in the right places.  If you take out one column, you will greatly have to beef it up to match 6/5 Sum (Mnb).

For a two story steel moment frame, a contractor is requesting to have the floor beam frame on top of the
first floor column, and the second floor column frame on top of the beam, as opposed to the column being continuous
and the beams attaching to the side of the column. what do you guys think?

Thanx for your input
