Moment Frame
Moment Frame
(OP)
Is it possible to create a rigid frame to resist lateral forces using a connection as shown in the attached sketch? Continuous beam running on top of columns.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

The lateral loads are relatively light (interior equipment stand).

RE: Moment Frame
Stiffeners are required?
Any other design guides for this type of connection?

Simpson and a few other folks make some premanufactured versions of these if you'd like to go that route. See link.

RE: Moment Frame
Stiffeners will be required in the beam web if web buckling requirements control. You would likely find it cheaper to just size the beam web such that it didn't require stiffeners. The bolts and top plate will be similar to the end plate moment connections struct mentions which AISC design guide 16 covers.
This should be sufficient to transfer moments. Make sure you check your deflections, these things will still sway a lot. Also, you'll probably want to make sure the bolts are pretensioned as with load reversals the bolts will tend to loosen if they're only snug tight.

so if really want a pinned connection, have a base plate, 4 bolts, with a single pin to the frame so the the frame is truly pinned.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
