Layers of Type X gypsum board serving as noncombustible protection for interior surfaces of wall and ceiling assemblies determined in accordance with Table (1) shall be installed in accordance with the following: 1. Each layer shall be attached with Type S drywall screws of sufficient length to penetrate the mass timber at least 1 inch. Approximate Weights of Construction Materials (from Hoyle and Woeste, ) Weight Material Material (lb/ft2) Ceilings Acoustical fiber tile Gypsum board (see Walls) Mechanical duct allowance Suspended steel channel system Wood purlins (see Wood, Seasoned) Light gauge steel (see Roofs) Floors Hardwood, 1-in. nominal Plywood (see Roofs) Linoleum.
Masonry load-bearing walls can also function as shear walls in addition to enclosing and dividing spaces Generally, one 1/2 in thick, type X drywall panel on each side of a wood stud wall gives a 1-h fire-resistance rating. False. An eave is generally horizontal and the rake is inclined A load-bearing CFS frame structure is generally. Instead, wood let-in braces, Portland cement stucco, and interior wall finishes of plaster or gypsum wall board provided lateral racking resistance. Most of the crawl space foundations used full-height concrete or masonry stem walls, not wood cripple walls that are .
For this purpose, there are two common ways which are; 1. use CFS composite beams in concrete slab systems, 2. as wall studs lined with gypsum plasterboard in residential buildings .

Contribution of gypsum wall board to racking resistance of light-frame walls. [Madison, Wis.]: U.S. Dept. of Agriculture, Forest Service, Forest Products Laboratory,  (OCoLC) Contribution of Type-X Gypsum Wall Board to the Racking Performance of Light-Frame Wood Shear Walls Article in Journal of Structural Engineering (5) January with 74 Reads.
This paper presents an experimental investigation of the racking performance of light-frame wood shear walls to evaluate the effect of Type X gypsum wall board (GWB).
Twelve shear walls sheathed with oriented strand board (OSB) alone, GWB alone, or in combination were tested under static monotonic or reversed cyclic lateral load.
using ASTM E standard to study the contribution of GWB to the racking resistance of light-frame walls. Tests were conducted with varying wall lengths, GWB orientation and wind bracings.
Wolfe concluded that GWB has a significant contribution in to racking resistance of the wall, which varies with panel orientation and wall length.
The tried-and-true Gypsum Construction Handbook is a systematic guide to selecting and using gypsum drywall, veneer plaster, tile backers, ceilings, and conventional plaster building materials.
A widely respected training text for aspiring architects and engineers, the book provides detailed product information and efficient installation.

This chapter. provides valuable information that explains what is involved in creating a proper connection in the wall and framing systems of coastal buildings. IRC Wall Bracing: A Guide Page 3 manner, offsets can affect braced wall panel location and, thus, the layout of openings for windows and doors in a series of braced wall lines on a given building side (elevation).
Braced Wall Line Spacing (R) – Braced wall line spacing establishes the amount of racking load that must be resisted by the two or more parallel braced wall lines in each File Size: 1MB. A key element in the seismic load resisting system of a wood framed structure is the shear wall which is typically sheathed on one side with plywood or oriented strand board (OSB) and gypsum on the other.
The shear capacity of gypsum sheathed shear walls is typically neglected in high seismic areas due to the susceptibility of conventional drywall screw connections to damage caused by by: 1.

Wolfe (page images at HathiTrust). corresponding wall stiffness to give its contribution to the total racking resistance of the structure. An example of this approach has been presented by Whittemore et al. This approach provides greater potential for the efficient design of light-frame racking walls than either the HUD or the Code approach.
However, it requires a. The proposed light-frame structure comprises steel columns for vertical loads and an innovative bracing system to efficiently resist seismic actions. This seismic force resisting system consists of a light timber frame braced with an Oriented Strand Board (OSB) sheet and an external technoprene plaster-infilled slab.
Steel brackets are used as foundation and floor by: 7. Gypsum wall board is certainly not recommended as the primary seismic bracing for walls, although it does contribute to the structural resistance of buildings in all seismic and wind conditions.
It should also be recognized that fastening of interior gypsum board varies in. Structural wall sheathing, such as plywood or oriented strand board, distributes lateral loads to the wall framing and provides lateral support to both the wall studs (i.e., buckling resistance) and the entire building (i.e., racking resistance).
Interior wall finishes also provide significant support to the wall studs and the structure. buy en amd 2 eurocode 5: design of timber structures - part general - common rules and rules for buildings from sai global.the wall of light Download the wall of light or read online here in PDF or EPUB.
