new interior metal stud walls; the partition types called for bracing diagonally every 4' OC (prototypes).

in richmond virgina they use slip track metal heads to attach walls to roof deck above....if the wall is extended all the way to the roof deck & attached with the slip track detail is the diagonal bracing still required by code?

No, not required

 

[Paul Sweet]

Diagonal bracing should only be necessary if the walls have to resist shear.Deflection track should be used everywhere, and not just in Richmond. This is what happens if it isn't specified, and the contractor puts up the partitions before putting the big HVAC unit on the roof.

Deflection tracks are only used in situations where the walls will not be used to resist lateral loads. The diagonal bracing provides lateral load resistance and is thus not needed when deflection tracks are used.

This is the type of question that should be resolved by the design professional.

The 4' OC bracing is a standard cut and paste detail the architects here in the Richmond area use for when we build walls to the underside of the ceiling grid. A diaginal brace attached perpendicular to the top of the wall and to the structure above. Depending on what county you're working in, will deternine if the wall needs to be braced as detailed. We also don't always use stip track when attaching a partition to the deck. It depends if the wall has a UL rating.

Had no idea there were this many Virginians around. Howdy neighbors.
