Live Loads

The live loads consist of people, furniture, equipment, wind, snow, and soil.  To design for the occupancy load, typically 50psf is used.  Furniture and equipment can vary depending on the building.  Wind exerts pressure or suction on the exterior of the building.  This is a lateral load as opposed to the vertical loads or people, snow, and equipment.  Snow loads are taken into account due to the pressure it exerts on the roof.  Typically the snow load used is 10psf.  Drift can occur, which causes a heavy load over a concentrated area.  Soil loads vary as a function of depth.  The further down into the ground you go, the heavier the load.
