Seismic Design 1

[Lion06]

Can anyone point me to some easy to read seismic design criteria? I'm reading through AISC 341, and I can only find a few required criteria for IMF.
A minimum interstory drift angle, a minimum Vu, and minimum capacities for FR moment connections.

I thought for sure there would be a requirement for the ratio of beam/column moment capacity and/or detailing requirements for reduced beam sections. I don't see any of that for IMF.

I also thought there would be some guidelines on reducing the beams sections, but I don't see that, either.

Does anyone know where I can find a good example to look through?

Thanks, slick. Have you done seismic design and detailing?

It looks like all of the prequalified connections use WF columns. Does that mean that HSS columns need to be tested?

I'm looking to do thru-plate moment connections for an IMF frame, but I don't see that as an option in FEMA 350.

You must use an OMF with HSS columns or qualify them with testing if you are going to use them in an IMF.

That questions refers to HSS beams, not columns.

Answer still applies.
