COMPOSITE LIMITING HEIGHTS
Notes:
– Allowable composite limiting heights were determined in accordance with ICC-ES AC86-2010.
– Additional composite wall testing and analysis requirements of the SFIA Code Compliance Certification Program were observed.
– In accordance with current building codes and AISI design standards, the 1/3 stress increase for strength was not used.
– The composite limiting heights provided in the tables are based on a single layer of 5/8" Type X Gypsum Board from the following manufacturers:
American, CertainTeed, Georgia Pacific, Lafarge, National, Temple Inland, and USG.
– The gypsum board must be applied full height in the vertical orientation to each stud flange and installed in accordance with ASTM C754-2008 using minimum No. 6 Type S drywall
screws spaced as listed below:
– Screws spaced a minimum of 16 in. o.c. to framing members spaced at 16 in. or 12 in. o.c.
– Screws spaced a minimum of 12 in. o.c. to framing members spaced at 24 in. o.c.
– No fasteners are required for attaching the stud to the track except as detailed in ASTM C754-2008.
– Stud end bearing must be a minimum of 1 inch.
f Adjacent to the height value indicates that flexural stress controls the allowable wall height.
s Adjacent to the height value indicates that shear/end reaction controls the allowable wall height.
