      <li>
        The allowable (ASD) loads are based on the 2015 National Design
        Specification for Wood Construction (NDS).
      </li>

      <li>
        Post heights are based on standard precut stud heights and associated
        top plate heights. Wall height is nominal height plus 1 1/8&quot;.
        Effective post lengths, l<sub><big>e</big></sub
        >, are the actual wall height minus the thickness of (3) 2x plates (4
        1/2&quot;).
      </li>

      <li>
        <span>Shaded</span> values are limited by the perpendicular-to-grain
        bearing load, P<sub><big>c</big></sub
        >&perp;, when posts bear on wood sill plates. Where posts and sill
        plates are different species, Designer shall limit allowable load to the
        lower of the post or the perpendicular-to-grain load for each species
        used.
      </li>

      <li>
        Perpendicular-to-grain allowable loads do not include the NDS Bearing
        Area Factor, C<sub><big>b</big></sub
        >. For posts whose bearing area is not closer than 3&quot; from the end
        of a sill plate, the P<sub><big>c</big></sub
        >&perp; values may be multiplied by C<sub><big>b</big></sub
        >.

          /><br />
          T<sub><big></big></sub> = Bearing Length (post thickness)<br />
          C<sub><big>b</big></sub> = Bearing Area Factor per NDS 3.10.4
        </p>
      </li>

      <li>Parallel-to-grain values listed. Assume strong axis buckling.</li>

      <li>
        Tension loads are based on net section assuming hole size equal to bolt
        diameter plus 1⁄16&quot;. Tension loads have been increased for wind or
        seismic loading with no further increase allowed; reduce where other
        loads govern.
      </li>

      <li>Values do not consider combined axial and out-of-plane bending.</li>

      <li>Bolt diameter &ldquo;None&rdquo; indicates full cross-section.</li>
