Wood-frame wood structural panel shear walls are prevalent in high seismic areas where lateral forces from seismic loading control the required length of shear walls. Relatively large design strengths and permitted use of up to 3.5:1 aspect ratio wood structural panel shear walls provide design flexibility to accommodate building configurations where total length of wall or aspect ratio of wall portions available for seismic force resistance is limited. Additionally, wood-frame wood structural panel shear walls are permitted for use in all SDCs and, in SDC D, E and F, are permitted with structural height of 65 ft. In contrast, wood-frame shear walls sheathed with other materials are generally associated with smaller values of design strength, most commonly used where large lengths of shear wall are available, not permitted in SDC E and F, and limited to a structural height of 35 ft in SDC D. In some cases, such as for structural fiberboard shear walls and particleboard shear walls, use of such shear walls for seismic force resistance is limited to SDC A, B and C only with a structural height of 35 ft in SDC C.
