RE: Drag Connection?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Don't know your specific case but with us a Drag Beam is a simple span
collector beam, typically at a sidewall, that collects forces from a
diaphragm type of system (Delta Joist for our case) and delivers it to a
vertical brace rod system to the foundation(s).  

The "use 3/8 thick angles" sounds pretty vague...  I assume they are talking
about the end connections of the drag beam but don't know for sure without
looking at the drawings... depending on the system that is connected to the
beam, the angles could be used to drag the force into the beam (connect into
the drag beam beam web or flange from the side).

Either case, I would ask the original engineer for further clarification and
to size the 3/8" angles (unless that is not his responsibility on this
project).

A steel detailer sent me this message:  "On this hospital project there is a
note that indicates several 'drag beam connections, use 3/8" thick angles.'
What does that mean?"

What's a DRAG BEAM?
