<h1>Compression Posts</h1>
  <div class="row">
    <div class="col-md-6">
        <p>Compression posts play an integral role in designing a Strong-Rod Anchor Tiedown System for shearwall overturning restraint. As tension loads are resisted by the ATS steel rods, adequate compression elements are crucial in the opposite end of the shearwall. Compression posts are either single members or multiple members.</p>
    </div>
    <div class="col-md-6">
        <p>A designer may use either a symmetrical or an asymmetrical post configuration. Simpson Strong-Tie offers guidance by providing standard tables for compression elements. Find more information on our <a href="/strongrodsystems_lateralsystems/landing">website</a>.</p>
    </div>
  </div>
 
  <h3 class="h4">Asymmetrical Posts</h3> 
  <p>This arrangement means that a maximum of three built-up studs at the end of the wall and multiple number of studs at the opposite side of the Strong-Rod. This provides uniform anchor placement and consistent end-of-wall placement location at upper floor levels. Multiple posts are not required to be fastened together unless otherwise noted by the designer.</p>

          <li>If condition utilizes three (3) end-of-wall
            studs, the interior side will have one

          <li>Maximum spacing between end studs and interior studs shall not
            exceed spacing specified in job specific run details.</li>
          <li>Top plate and strap terminations shall use two (2) end studs all levels.</li>
          <li>Bridge block terminations shall use two (2) end studs at the
            uppermost level when a single jack is specified and shall use one (1)
            end stud if a double jack is specified (see job specific run details for
            jack specifications); all other levels shall use two (2) end studs.</li>
          <li>Additional lumber should be added at the uppermost level as
            needed for end of wall framing.</li>
          <li>A minimum of one (1) interior stud is required at all levels.</li>
          <li>At any floor level, a maximum of six additional studs may be used at
            the interior studs as compared to the interior stud pack above.
