designing metal stud track to accomodate vertical deflection

designing metal stud track to accomodate vertical deflection

(OP)
any recommodations on what methods or tables or resources to use to verify the amount of vertical deflection to design for accomodating in the head track of metal stud walls?  

I see some of the ways to allow is via single deep leg track, double track, slotted track or slotted clip angle...

AISI has a wall stud design methodology.

is there a simple design table an architect can use on the internet somewhere?

RE: designing metal stud track to accomodate vertical deflection

The best resource, of course, is the EOR as to how much deflection to consider for a particular structure.

In lieu of that, I would make some assumptions on deflections. Assume that dead load is already in the structure before the studs are erected. Then use typical deflection ratios based upon the span of whatever you are connecting to. Assume 100% of the live load is applied.

L/360 for floors
L/240 for roofs of conventional structures
L/120 for roofs of PEMB

For concrete structure, provide for long term creep.

Don't forget that if you are connecting to a beam supported by a girder, that you will have to add those two deflections together and then provide for additional allowance for clearance.

A slip track needs to be sized not only for the vertical deflection but also to resist the internal pressure of 5 psf on the studs (or the C & C wind load if an exterior wall)since the flanges will need to bend to resist the lateral force from the stud. Use slotted clips where the slip track will not work. Rated walls may require modification of these details to maintain rating and still allow movement.

I know of no tables since each condition is unique.
