Since you only need to support the weight of the concrete walls, could you just design a strip of the base slab under the walls to transfer the weight into the soils?. Model complex reinforced concrete shapes, including curves, sloping, or non-orthogonal shapes using intuitive commands. Four to eight inch thick concrete slabs are mainly used for driveways, patios, sidewalks, and garage floors. 1-Go to slab thickness and define your slab similar to this picture. Concrete slabs can be used to create pathways, walkways, patios, driveways and much more. Slabs or foundations can be of any shape, and can include edges shaped with circular and spline curves. The three concrete design modules design reinforced concrete columns subjected to axial force and bi axial bending. Permanent Joint Fillers. The USC School of Architecture is Southern California’s oldest architecture school and the only architecture school connected to a private research-1 university on the West Coast. Another practice is to take pressure as liquid pressure due to concrete poured in 3/4 to 1 hour only as by then, the concrete below that level would have set and became solid. A floor slab with a minimum concrete compressive strength of 2,500 psi and a minimum thickness of 5” or 6” is normally required in. 8 Shear area Design of Reinforced Concrete Beams 47 0.
