Vertical load consists of dead load and live load. The weight of the formwork plus the weight of the freshly placed concrete is dead load. The live load includes the weight of workers, equipment, material, storage, impact, etc.
3. Live load. The American Concrete Institute (ACI = 347) specifies that different elements used to support vertical loads should be designed for a minimum live load of 50 psf on the horizontal projection. When motorized cars are present, the minimum live load should be 75 psf.
The minimum design load for combined dead and live load should be 100 psf, or 125 psf if motorized cars are present.
