Simple formulae to determine the elastic stiffness and first yielding shear strength of sheathed walls with any nailing arrangement pattern and with any size of sheathing material are formulated using the analogy of the moment inertia of a section, sectional coefficient, and plastic sectional coefficient. Load-deformation relationships from elastic to plastic regime of sheathed walls are also computed by extending these formulae to non-linear analysis. Shear tests on sheathed walls with three kinds of nailing patterns and with two kinds of sheathing material sizes were carried out. Non-linear finite element analyses were also carried out to verify the set of formulae. It was found that these formulae are sufficiently accurate to enable the behaviour of sheathing materials nailed on to frames with high flexural stiffness to be evaluated. Simplified formulae to predict the elastic and plastic behaviour of sheathed walls were derived from the regression analyses based on the 759 parametric studies.
