AbstractFor over fifty years, many agencies have been performing racking tests on wood frame walls to determine their shear resistance. The racking strength of walls is derived from the interior finish as well as the exterior sheathing and siding. This is discussed in the context of Canadian tests which eventually led to the deletion of building code requirements for bracing and sheathing. Comparisons between Canadian and U.S. test results indicate generally reasonable agreement with certain materials, while others show substantial differences. Allowable shear values given in US model building codes are summarized. Mathematical models for computing racking strength from the lateral strength characteristics of fasteners are discussed. Design aids for computing the shear resistance of wood frame walls are noted.
