What is the allowable shear value for wood structural panel sheer walls utilizing staples with Douglas-Fir larch seismic loading for a 3/8 panel thickness?

The allowable shear value for wood structural panel shear walls using staples with Douglas-Fir larch under seismic loading conditions is recognized to be 235 pounds per linear foot for a 3/8 inch panel thickness. This value is derived from established design codes that specify the shear capacities of wood shear panels based on factors such as wood species, fastener type, panel thickness, and loading conditions. The designation of 235 takes into account the material properties of Douglas-Fir larch, which is known for its strength and performance in shear applications, particularly in seismic situations where adequate resistance to lateral forces is critical.

The other values listed, while seemingly plausible, do not correspond with the uniformly accepted ratings specified in engineering guidelines for panel shear walls. Therefore, the answer of 235 is in alignment with the current standards set forth for structural design when utilizing wood structural panels in seismic applications.
