<br /> General Assumptions for Trus Joist� Beams Beam Orientation
<br /> ■ Lateral support is required at bearing and along the span at 24"on-center,
<br /> maximum.
<br /> �-
<br /> ■ Bearing lengths are based on each producYs bearing stress for applica6le grade and
<br /> orientation. ''=
<br /> ■ All mem6ers 7�"and less in depth are restricted to a maximum deflection of�/c". ��
<br /> ■ Beams that are I�i"x 16"and deeper require multiple plies. ��'
<br /> ■ No camber.
<br /> • Beams and columns must remain straight to within 5L'/acoa(in.)of true alignment.
<br /> L is the unrestrained length of the member in feet. COlUmtt 01'IBlttet1011
<br /> ■ Tables on pages 8-15 include load reductions applied in accordance with code.
