A403.11.2.3 Wood Species of Framing Members

Existing Building Code 2009 > A4 Earthquake Hazard Reduction in Existing Woodframe Residential Buildings With Soft, Weak or Openfront Walls > A403 Analysis and Design > A403.11 Wood-Framed Shear Walls > A403.11.2 Wood Structural Panels > A403.11.2.3 Wood Species of Framing Members
JUMP TO FULL CODE CHAPTER
Allowable shear values for wood structural panels shall consider the species of the framing members. When the allowable shear values are based on Douglas fir-larch framing members, and framing members are constructed of other species of lumber, the allowable shear values shall be multiplied by the following factors: 0.82 for species with specific gravities greater than or equal to 0.42 but less than 0.49, and 0.65 for species with specific gravities less than 0.42. Redwood shall use 0.65 and hem fir shall use 0.82, unless otherwise approved.
