Limiting Heights <br /> Drywall Studs without Contribution Due to <br /> Gypsum Wallboard C) <br /> TION: NOTES: <br /> exon of nor ially loaded ir7t,er r•wall studs subjected to un rm 1 National building codes generally describe the lateral <br /> 4s load on ars interior partition and assembly as a special <br /> load, not a wind load. As a result, the 1 allowable <br /> stress increase, allowed by the AISI Specification fvr <br /> La stud, in terms of sparing rinohes O.C.,lateral load 1 SR, and wind Ioaded elements,is not applicable. <br /> on limit which provides ars allowable height equal to cr greater than <br /> project requirements. 2. Limiting heights are based an the stud alone without contribution <br /> due to the attachment of the gypsum wallboard.See Page 7 for <br /> limiting height values accounting for the in callation of gypsum <br /> board products.Framing and gypsum wallboard shall be installed <br /> in accordance with ASTM Specifications C 754 and C 840. <br /> Limiting heights assume the section is br-aced against minor axis <br /> rotation by the proper attachment of gypsum wallboards or cher <br /> sheathing products of equivalent or greater strength w each facec) <br /> of the wall,Mechanical bridging.sDaced at verUc,,al intervals not to <br /> exceed 5"-T an center, may be substituted in conditions where <br /> sheathing is not installed tUl height each side or to one side only, <br /> 4.
