I was asked about
using live load to resist uplift from snow load. The situation is wood
trusses spanning 30 something feet sitting on the cantilevered ends of
wood joists. The designer wants to use live load so that the interior
end of the joists do not need an uplift connection and the ends of the beam
supporting cantilevered joists does not need an uplift
intuitive to me that you should not use live load to resist uplift from snow
because live load is make-believe and can be removed by definition and the live
load and snow load would not necessarily occur at the same
I cannot find a code
section or notes next to load combinations that says you cannot do
this. However, I seem to remember a local home builders floor that started
to bow up before the 2 feet of stacked newspapers could be put on the
Does the code allow
you to use live load to resist uplift from snow? Does anyone ever use live
load to resist uplift from snow or other live load for that
