Metal Stud Flange Bearing

[otto_eng]

Hi,

I am designing a metal stud wall for lateral and gravity. I'm planning to connect a metal track to flanges of the studs in order to carry the ceiling joists. I can not let them sit directly on the studs.
I was wondering if that would be an adequate design or not since 20 GA metal stud is not really thick. The shear on the connections is only 150 lb D+L.

Thank you,

The detail that you describe is typical. The roof joists usually sit on the top track. The joists should be checked for web crippling.

Attached is a guide with typically light gauge details.

Hi ash060,

Thanks for your response but the wall is sticking in so I can not let them sit on the top track.
I need to attach roof joists to the metal track (ledger ) and the metal track ( ledger ) to the studs.

You need to know a little more than what you have stated. How are the wall studs braced? Dry-wall or bridging? In-plane or out-of-plane? Start with Cold Formed Steel Engineers Institute CFSEI

Provide a continuous cee ledger along the face of the studs and screw to the face of the wall studs. Just provide enough screws for the applied load.
