Contribution Of Gypsum-Board Sheathing To The Compressive Resistance Of Wood Studs Subjected To Gravitational Loads, Daniel J. Grenier

Electronic Thesis and Dissertation Repository

Gypsum board is the most commonly used sheathing material in Canadian residential construction. Current Canadian standards recognize the role of gypsum-board sheathing in bracing studs to prevent weak-axis buckling and in resisting in-plane shear, but do not recognize its potential contribution to axial compressive resistance of a sheathed wall. The research in this thesis, therefore, investigates this contribution for light-frame wood stud walls sheathed with gypsum-board on both sides of the stud. The axial compressive resistance of bare and gypsum-board sheathed studs were computed using new finite element models that account for the nonlinear wood stress-strain relationship and nonlinear shear …
