WebGround snow loads are converted to top chord live loads when ordering trusses. Design loads: Expressed in psf (pounds per square foot). The amount of packed snow for the … WebIf a building is designed for snow loads, for example, they probably know the roof trusses can be designed with a 1.15 load duration factor. On the other hand, if wind is the controlling factor, they know roof trusses can be designed with a C D = 1.6. But that’s probably where the understanding of load duration ends. coldice freezer packs
