How to Calculate Steel in RCC Slab?

BBS for Slab-

Bar bending schedule or bbs plays a significant role in estimating the quantity of steel for beams, columns, and slab. It helps to find out bar shape, size, length, weight, bending dimension, etc. In two way slab, the slab is supported by four sides and loads are carried along with both directions.

How to Calculate Steel Quantity for Slab:

• Step 1. Number of Main Bars & Distribution Bars.
• Step 2. Calculate the Cutting Length of Bars.
• Step 3. Total Weight of Slab Steel.

Steel Quantity-

This can be done by multiplying cross-section area of steel by its total length by density of steel which 7850 kg/m³. Total steel quantity of column equal to the sum of both main and stirrup steels.

Steel Required Per Square Feet-

If we take last thumb rule point, thumb rule for steel in RCC structure is 3.5 Kg to 4 kg/ sq.ft. of built-up area. 3500 Kg to 4000 Kg of Steel quantity is required for construction of 1000 square feet house.

Reinforcement in Slab-

Structural reinforcement is typically placed in the bottom portion of the slab thickness to increase the slab’s load capacity. Most structural slabs-on-ground have both top and bottom layers of reinforcement for controlling crack-widths and increasing load capacities.

How to Calculate Steel in Rcc Slab?

The Thumb rule to calculate steel in slabs is 3.5 kg to 4 kg/sq. ft of built-up area. On the whole, approximately 3500 kg to 4000 kg of steel is required to build a 1000 square feet structure.

Steel Required for Slab

The Thumb rule to calculate steel in slabs is 3.5 kg to 4 kg/sq. ft of built-up area. On the whole, approximately 3500 kg to 4000 kg of steel is required to build a 1000 square feet structure. This is one of the most basic important information that one must be aware of before building his/her own dream house.

Rcc Slab Steel Calculator

Determine the dimensions of the slab (Length, Width, and Thickness).
Let’s assume the dimensions of the slab are:

Length = 6 meters
Width = 4 meters
Thickness = 0.15 meters

Steel Calculator for Slab

Determine the steel reinforcement required for the slab.

The amount of steel reinforcement required for a slab is usually expressed as a percentage of the total cross-sectional area of the slab. The percentage varies depending on the type of slab and the loads it will be subjected to. For a general-purpose RCC slab, we can assume a steel percentage of 1%.

Area of the slab = Length x Width = 6 x 4 = 24 square meters

Steel reinforcement required = 1% of the area of the slab = 1/100 x 24 = 0.24 square meters

Roof Slab Steel Calculation

Calculate the volume of the slab.

• Volume = Length x Width x Thickness
• Volume = 8 x 6 x 0.15
• Volume = 7.2 cubic meters

Area of Steel Formula in Rcc

As per thumb rule steel quantity required in the formation of RCC beam should be 2% of total volume of concrete. To calculate the steel quantity in beam as 2% of volume of concrete = 0.02 x 7850 x 5.29 = 830 kg.

Slab Steel Calculation

The total steel quantity per slab must be equal to the total amount of main steel and stirrup steels. In simple terms, one can just multiply the length of the slab by its width and then divide the area by 12.5.

Roof Rod Calculation

Calculate the total surface area of the roof slab in square meters.
The surface area of the roof slab can be calculated as follows:
Total surface area = Length x Width
Total surface area = 10 x 8
Total surface area = 80 square meters

Tmt Bar Calculation for Roofing

The area of each TMT bar can be calculated as follows:
Area of each bar = (pi x diameter^2)/4
Let’s assume we are using 12mm diameter TMT bars.
Area of each bar = (3.14 x 12^2)/4
Area of each bar = 113.1 square millimeters

Steel Calculation for Slab Online

1. Open your preferred search engine and search for “Online Steel Calculation for Slab” or similar keywords.
2. From the search results, select a reliable and trustworthy website that offers a steel calculation tool for slabs.
3. Once you are on the website, enter the required details of the slab such as length, width, thickness, and spacing between the steel bars or rods.
4. The online steel calculation tool will then automatically calculate the amount of steel required for the slab and display the results on the screen.

Slab Size in Mm

In a residential building it is 9 ʺ × 12 ʺ or 225 mm × 300 mm standard size according to (IS codes). The minimum RCC beam size should not be less than 9 ʺ × 9 ʺ or 225mm × 225mm with the addition of a 125mm slab thickness. The size of the columns depends on the total load on the columns.

Rcc Slab Calculation Formula

To calculate the amount of concrete required for an RCC (Reinforced Cement Concrete) slab, you can use the following formula:

Volume of concrete = Length x Width x Thickness

Where:

• Length is the length of the slab in meters
• Width is the width of the slab in meters
• Thickness is the thickness of the slab in meters

Steel Required for Slab Per Square Feet

The amount of steel required for an RCC (Reinforced Cement Concrete) slab per square feet depends on several factors such as the design, thickness, and the spacing of the steel bars. As a general rule of thumb, the amount of steel required for an RCC slab is typically between 0.5% to 2% of the total volume of concrete.
