The 6 inch suspended slab in detail 21 weighs 75 pounds per square foot but the formwork should be designed to carry psf due to the weight of workers and equipment used during pour That is why concrete formwork for suspended slab has a lot more columns and beams compared to the normal residential floor framingThe simplest type of twoway slab to construct is known as a flat plateThese slabs are supported directly by the columns and have a completely flat soffit For live loads of about 50 psf (25 kPa), column spacing typically ranges from 15 to 25 ft (45 to 75 m) with minimum slab thicknesses of 6 to 10 in (150 to 250 mm)1 For longer I'm designing a suspended concrete slab over a concrete basement walls for a house garage 24'X24' plan dimension Ideally I would like to avoid beams, but I know locally (Missouri) it has been done with one or two steel W shape beams to support the slab

1 Reinforcement Details of Simply Supported Beam and Slab As seen in figure1 below, for a simply supported beam and slab, 100% reinforcement as per the design is provided as tension reinforcement at the mid span of the beam and slab, and 50% is curtailed at the distance of 008L from the center support 2 Torsion reinforcement shall be provided at any corner where the slab is simply supported on both edges meeting at that corner and is prevented from lifting unless the consequences of cracking are negligible It shall consist of top and bottom reinforcement, each with layer of bars placed parallel to the sides of the slab and extending from the edges a Suspended Slabs are typically buildup in two ways 1 Precast concrete Unlike onsite concrete pouring, a leading manufacturing approach is used to produce highquality precast concrete in a restrained factory environment The reinforcement is placed in reusable and adjustable molds, and the concrete is poured, vibrated and cured
