Structural steel may be rebar or WWF. Macro synthetic fibres. 2—Example with amount of steel and slab joint spacing predetermined. Grade slab itself acts as a foundation for the building which does not require further footings. The floor below was designed to have a U-value of 0. Shallow foundations include spread footing foundations, mat-slab foundations, slab-on-grade foundations, pad foundations, rubble trench foundations and earthbag foundations. Slab foundations are more common in southern states with warm climates, where the ground is less likely to freeze and cause the foundation to crack. 1—Introduction. Figure 4-a is the illustration of a post-tensioned ground-supported slab with tendons located below the slab centroid. While considering the various load combinations, the nodal displacements of the slab on the ground make it possible to check the stability and deflections of the structure. 89 k-ft φ Mn = 3. Common examples of track transitions include: bridge approaches, tunnels, grade crossings, and transitions between sections of ballasted and ballast-less track (or slab track). Design the slab, following the provisions of the ACK Code. Design of Foundations: PDF: 1. Use three or four continuous #4 rebar all around the perimeter of the slab turn-downed edge at a minimum, but final determination will depend upon local building codes.
