Assume area of circle= area of square
πd2/4=L2
L=0.88263 x d
Deduct the cover from L from both sides. This will be length of bar

Supended slab are slab not sit on the ground directlySuspended slab is a slab supported by beams.
1. one way slab 2. two way slab 3. flat slab 4. roof slab
A solid slab is a reinforced concrete slab which is supported by beams or walls..
when the length of the slab is more or equal to twice the breadth hence it has to be one way slab.
V of a circular slab = thickness of the slab multiplied by (pi multiplied by the radius2)
If you know the dimensions of the slab, assuming that the slab is solid and in the shape of a rectangle, box, or square, you can calculate the volume with the formula: LxWxH which is length times width times height. This will give you the volume of the slab in cubic units (meters, feet, inches, whatever). Depending on the type of steel, you will have a different density ratio which can be used to calculate the weight of the slab. The density of low grade steel is something on the order of: 7850 kg/m3 so you would multiply your volume by the density ratio to get kilograms. If you know the weight of the slab and the type of steel, you can calculate the volume by dividing the weight by the density ratio. I hope this helps, perhaps you could provide more details on the type of steel and the exact property of the slab that you need (volume, weight, density.
You may increase the slab thickness and/or calculate the steel reinforcement required to withstand against the applied shear stress.
well , reinforcement steel required for slab is nearly 0.7 to 0.8% of the volume of concrete so if concrete is 1 cum then steel will be 1*0.7/100 =0.007 but density of steel is 7850 kg/ cum so 0.007*7850=54.95 say 55 kg per cum so steel required to reinforce 1 cum concrete for slab is approximately 55 kgs.
The minimum area of steel required in RCC slab as per BS code is 0.12 to 0.15% of total area. The maximum diameter of bar in slab, shall not exceed D/8, where D is the total thickness of slab.
About 2.27 kg of steel bars is used for the RCC slab of size 50' 18' 4.5.
Multiply the length by the breadth. eg if slab is 2 ft by 3 ft then area of slab = 6 sq feet
A conventional slab will have two bars side by side near the top and bottom of each beam and a 16" grid across the entire top of the slab. Can't help you with a post tention... they are inventing new ways to take steel out of them every day.

well..dead load is calculated by the weight of all quantity of materials used for your slab, beam, column and foundation. though the structure is built from bottom, its analysis is always done from the top..
Drill out the edge of the slab and add some dowels....or cut the slab back.
Ans: One way slab is the slab having ratio of longer span to shorter span equal to or more than 1.5 . If the ratio of longer span to shorter span is equal to or less than 1.5, then such slabs are called as two way slab. In one way slab main tensile reinforcement is placed parellel to shorter side which will be the main steel, where as in two way slab both direction required main steel.
