## 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:-

- Deduct the cover for finding length of bar.
- Evaluate the length of the distribution bar.
- Calculate the Value of ‘D’ (Depth of slab- Top cover- Bottom cover)
- Find out the No. of Bars.
- 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.

- Simply Supported Slab = Span / 20.
- One End Continuous Slab = Span / 24.
- Both End Continuous Slab = Span / 28.
- 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.
