# Introduction of BBS of One Way Slab and Estimation of Steel Quantity

0

A One Way Slab is a type of concrete structure where the concrete is supported on only two opposite sides. This type of slab is typically used for pavements, balconies, and industrial floors. The other type of slab is a Two Way Slab, where the concrete is supported on all four sides.

Determining the amount of steel reinforcement required for a One Way Slab is a complex engineering calculation. This article will provide an overview of how to calculate the steel quantity for a One Way Slab. The first step is to determine the loads that will be applied to the slab. These loads can come from many sources, such as, vehicles, people, and equipment. The next step is to select the appropriate concrete

## Weight Calculation of Main Bar of BBS of One Way Slab

• The weight of the main bar of the BBS of a one way slab is calculated by first determining the volume of the main bar, and then multiplying that by the density of the material
• To determine the volume of the main bar, the length, width, and height of the main bar must be measured
• The density of the material can be found in a variety of ways, but the most common is to look up the density of the material in a reference book.

## Calculate Cutting Length of Single Piece of Distribution Bar of BBS of One Way Slab

• The cutting length of a single piece of distribution bar of BBS of one way slab can be calculated as follows:
• Cutting length = (Length of one way slab * Width of one way slab) / (Number of distribution bars)
•

For example, if the length of the one way slab is 20 feet and the width of the one way slab is 10 feet, and the number of distribution bars is 4, then the cutting length of a single piece of distribution bar will be 50 feet.

## Calculate Total Requirement of Reinforcement for the BBS of One Way Slab

• The BBS of one way slab can be calculated by using the formula:BBS = (Wu / (A * fc)) * (L / s)

where,

Wu = Ultimate load on the slab
A = Area of the slab
fc = Concrete strength
L = Length of the slab
s = Spacing of the reinforcement
