Concrete floor slabs on grade are often subjected to heavy loads in buildings such as wall loads, stationary live loads and DESIGN OF GRADE SLAB. 4—Other PCA design information. 9 m³; Concrete weight = 0. Concrete Thickness For flatwork, such as slabs-on-grade and driveways, a minimum thickness of four inches is required, but increasing the thickness to five inches can add nearly 50 percent to the load-bearing capacity. With some limitations, reinforcement for slabs can be sized using the Subgrade Drag Theory in order to increase the spacing of control or construction joints. from top of slabs not exposed to weather. The two design options are a ground-bearing slab, or a pile supported suspended slab. A common example of a moving load would be a forklift used in a warehouse. This is usually a mistake as pre-cast utility and pipe protection slabs and standard design details are often very lightly reinforced and not designed o take significant imposed loadings, particularly where the slab needs to span over a wide trench.
