ANALYSIS OF CONCRETE SLABS SUPPORTED ON

Resumen: A numerical model for material non-linear analysis of concrete slabs supported on soil is described in this work. In this model, the cracked concrete is regarded as cracks with concrete between cracks. The behaviour of

Strengthening of Cutouts in Existing One-Way Spanning R. C

Description of Tested Slabs. The experimental program consisted of testing five (one-way spanning R.C. slabs) with an overhang. All slabs were prismatic, rectangular in cross-section and nominally 2000 mm long × 1000 mm width × 100 mm thickness with a clear span (distance between supports) of 1200 mm and a cantilever 700 mm long.

Three Myths About Contraction Joints in Residential Slabs

Dec 13, 2017 · For plain and reinforced concrete, the slab-on-ground may be isolated or monolithic with the footing. When isolated, the first joint next to the footing can have a spacing up to that given in Table 1. For example, if slab thickness is 4 inches, the first joint can be 11.5 feet away when using concrete with ¾-inch maximum size aggregate.

Reinforced Concrete Slab - an overview

Reinforced concrete slabs, at least those designed to span in one direction, are no different conceptually from any other beams, with the following three caveats.First, only 3/4-in. concrete cover is required (see Table A-4.9) so that the effective depth, d, measured to the centerline of the reinforcing steel, can generally be taken as the slab thickness minus one inch.

Joints in Concrete Construction

Joints in concrete construction are construction, expansion, contraction and isolation joints. These joints are placed in concrete slabs and pavements at regular intervals to prevent development of cracks in concrete.

How to Cut a Concrete Slab

For larger slabs, a general rule is to take the slab thickness in inches and double that number in feet to determine joint placement. For example, if you have a 4-inch-thick slab, double the number 4: Cut a control joint every 8 feet or less. For a 5-inch slab, control joint maximum distance would be 10 feet.
