Gypsum Board Shear Values BigMount Heavy Industries

We have gypsum board shear values,Shear values for parallel appliion exceed those for perpendicular appliion, 3. Shear values for ⅝ in. (15.9 mm) gypsum board exceed those for ½ in. (12.7 mm) gypsum board, 4. Shear values increase with closer spacing of perimeter fasteners, and 5. When compared to other shear test results, shear values for screws are higher than for nails.

Retrofitting Gypsum. RETROFITTING / REROOFING POURED GYPSUM DECKS The poured gypsum roof deck consists of steel bulb tees, a form board (usually composed of gypsum or fiberglass), wire reinforcing mesh, and the gypsum concrete. The bulb tees, which are very strong vertically but quite flexible horizontally, provide the long span strength.

Behaviour factor evaluation of CFS shear walls with gypsum

ColdFormed Steel Framed Gypsum Shear Walls: InPlane

Coldformed steel (CFS) framed gypsum shear walls are common elements on lightframe structures, and they may be designed as the primary lateral forceresisting (LFR) system or function as secondary LFR elements. This paper presents the results of monotonic and reversed cyclic gypsum shear wall tests and discusses wall performance in detail.
