In most cases, answers to questions regarding dimensions, load ratings, hole patterns and spacing, etc. If you look at the illustration below, you'll note that a P1773 bracket is rated for design loads ranging from 450 pounds when used with 16 gauge P2000 up to 900 pounds when attached to 12 gauge P1000. For the purposes of this exercise, we'll assume our customer is curious about a Unistrut P1773 bracket. For other load conditions refer to page 18. For concentrated midspan point loads, multiply beam loads by 50 and the. Deduct channel weight from the beam loads. For pierced channel, multiply beam loads by the following factor: 4. After you open up the PDF version of our catalog-or your hard copy, begin by consulting pages 91-93. for reduction factors for unbraced lengths. That said, if you consult the Unistrut Engineering Catalog, the answer to this type of question is right at your finger tips. In this case, our customer didn't specifiy a particular bracket-or the channel size. Beam loads are based on a simple span and assumed to be adequately laterally braced.
