How tall can metal studs go

Knockouts are punched 12" o. Caution must be exercised when installing studs so knockouts align for bridging. Based on stud length, the distance the knockout falls from the tail end of the stud may not be the same from the lead end.

To align punchouts, make sure to use the same end in the same direction consistently. Skip to main content. Structural Studs. Found In:. Thickness: 33 mils 20ga , 43 mils 18ga , 54 mils 16ga , 68 mils 14ga and 97 mils 12ga. All studs are color coded for easy identification. Technical Data. Full structural framing technical design guide While this Design Guide Catalog is quite comprehensive, it does not completely cover our vast and growing lineup of products or design tables. Deflection The main purpose of specifying an allowable stud lateral deflection for interior wall framing is actually for determining what is an acceptable deflection for the wall facing materials.

See all design notes on the bottom of the lookup tool and tables. The studs for these framing systems must be able to withstand: The weight of the cladding material metal, stone, tile, etc. The wind loads to which they will be subjected. Deflection The main purpose of specifying an allowable stud deflection for curtain wall framing is actually for determining what is an acceptable deflection for the wall facing materials.

Also, the live load reductions for the walls were based only on the incoming tributary load area from each joist at the wall member. With the tributary area calculated per supporting member as one third of the incoming span, and the wall as a discrete bearing element — an entirely acceptable methodology in some circles — the height of the SFIA Matsen Tower becomes 48 stories.

Will building owners clamor to erect story CFS-framed structures? Maybe in the future, if the design proves to be economical.

If you wanted to build with cold-formed steel CFS framing, how high could you go? Sign in. The size, height and spacing of studs shall be in accordance with Table TABLE Listed heights are distances between points of lateral support placed perpendicular to the plane of the wall.

Increases in unsupported height are permitted where justified by an analysis. Shall not be used in exterior walls. Utility- grade studs shall not be spaced more than 16 inches on center or support more than a roof and ceiling, or exceed 8 feet in height for exterior walls and load-bearing walls or 10 feet for interior nonload-bearing walls.

Joined Oct 22, Messages If it is an interior wall with no load other than the sheetrock, a minimum of 5PSF should be used. If other loads such as shelving are probable, the loading shouldl go up accordingly. Many structural steel manufactuerer's have matrixes for these type of issues.

Depending on loads, spans, etc. Mark K Platinum Member.
