Shear Walls For Steel Stud And Gypsum Sheathed Light Gauge

4 2 3 2 type w screws are designed for attachment to wood framing.

Shear walls for steel stud and gypsum sheathed light gauge. The studs must be doubled at the shear wall ends. Framed walls with 20 gauge flat strap x bracing on the face type a. Table 3 is for seismic loads resisted by walls sheathed with plywood osb or steel sheet as indicated on one side only. Maximum stud spacing for a single layer application of 1 2 in.

And framed walls with 12 5 mm 1 2 in single ply gypsum wallboard on the back 12 5 mm 1 2 in gypsum sheathing. Table 1 also includes walls sheathed with steel sheet on one side. 12 7 mm and 5 8 in. The design of walls is often complicated by the lack of analytical methods for the evaluation of the strength and rigidity.

How about the light gauge steel studs. Framed walls with 12 5 mm 1 2 in single ply gypsum wallboard on the back and 12 5 mm 1 2 in single ply gypsum sheathing board on the face type b. Sheathed light gauge steel lgs shear walls are often used in structures as load bearing elements against wind and earthquake actions. Where can i find the allowable shear stress for this light gauge steel stud shear wall.

Using type s or w screws at different spacings. The cfs framed shear walls with steel sheathing and gypsum boards can achieve high shear resistance and good seismic performance 24. The findings provided a basis for continued research and development efforts leading to. 4 2 3 1 trim head screws shall not be used for the application of gypsum sheathing.

The shear wall is light gauge steel stud with plywood sheathing. If the studs are wood there is tables in ibc chapter 23. Ii shear wall values for light weight steel framing preface this report presents the results of monotonic and cyclic tests of 42 full size cold formed steel framed shear walls sheathed with plywood oriented strand board osb and gypsum wallboard gwb. Design by testing is a possibility if large numbers of identical walls are.

The details of the shear walls deviate from tested configurations in aisi s213 in that a a ledger or rim track is attached to the interior face of the walls b a gypsum board is attached to the interior face of the walls c osb panel seams do not always fall at stud or track locations and thus strapping must be used for shear transfer in. In this paper the seismic performance of cfs shear walls sheathed with steel sheet and gypsum board is studied. 15 9 mm gypsum board is. Use 20 gauge steel studs for exterior non loadbearing curtain wall systems.

Shear values for screw application of gypsum board on walls a series of tests was conducted in accordance with astm e72 to determine the shear resistance of gypsum board applied to one side of wood stud partitions 16 in. Also use them for interior partitions to provide more rigidity or greater heights than can be attained with standard 25 gauge studs. This paper presents detailed results on the shear behavior of 2 44 m by 2 44 m light gauge steel stud walls for three different shear resisting systems.
