How is slab design load calculated?

How is slab design load calculated?

Slab Load Calculation = 0.150 x 1 x 2400 = 360 kg which is equivalent to 3.53 kN. Now, If we consider the Floor Finishing load to be 1 kN per meter, superimposed live load to be 2 kN per meter, and Wind Load as per Is 875 Near about 2 kN per meter.

How do you calculate slab span?

Basics of Reinforced Concrete Slab Design. 1. Effective Span of Slab….2. Thickness of Slab.

Type of slab Ratio of span to depth
Simply supported and spanning in one direction 30
Continuous and spanning in one direction 35
Simply supported and spanning in two directions 35
Continuous and spanning in two directions 40

How is slab reinforcement calculated?

Steps to calculate the Reinforcement required for Slab:-

  1. Deduct the cover for finding length of bar.
  2. Evaluate the length of the distribution bar.
  3. Calculate the Value of ‘D’ (Depth of slab- Top cover- Bottom cover)
  4. Find out the No. of Bars.
  5. Compute the Total wt of steel required for slab reinforcement.

What is the concrete formula?

Use the formula. Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

What is a supported slab?

A simply supported slab is one type of slab with its ends simply supported on two walls or beams free to bend at the ends without any restraint unlike a fixed beam. This has only one span. A continuous slab has number of supports at series manner. In other words a continuous slab has more than one span.

How do you design a slab thickness?

Standards like ACI 318 have specified the minimum thickness of the slab based on the span of the slab.

  1. Simply Supported Slab = Span / 20.
  2. One End Continuous Slab = Span / 24.
  3. Both End Continuous Slab = Span / 28.
  4. Cantiliver = Span / 10.

How do you calculate design load?

For a 6″ thick wall with 4 meter height and 1 meter length, the load can be measured per running meter equivalent to 0.150 x 1 x 4 x 2000 = 1200 kg which is equivalent to 12 kN/meter. The load per running meter can be measured for any bricks type by following this method.

What is the maximum span of a slab?

The allowed recommended span lengths for continuous slabs are equal to 13.6m for two-way slabs and to 12.5m for unidirectional slabs. The published recommendations resulted in that the constant depth slabs are erected worldwide with the maximum span limit set at around 12÷13m.

What is minimum thickness of slab?

Minimum thickness should not be less than 4.75 inches not forgetting the factor of safety. Standard concrete floor slab thickness in residential construction is 4 inches, five to six inches is recommended if the concrete will receive occasional heavy loads, such as mortar homes or garbage trucks.
