Unbalanced Snow Loads

Column

Unbalanced Snow Loads

  • A new provision was introduced to the wood truss section (i.e., R810.2) of the 2006 edition of the IRC that permits the use of roof snow load computed using 0.7pg. 
  • Engineered design, through ASCE 7, is required in instances where the limitations on which the IRC is based are exceeded. 
  • ASCE 7 snow load design provisions require the evaluation of other conditions that may produce load surcharges in addition to the balanced uniform loads of pf or ps.
