Introduction of BBS of Beam Reinforcement and Steel Quantity
There are many methods of beam reinforcement, and the choice of method depends on the type of beam, the load on the beam, and the desired strength of the beam. One common method of beam reinforcement is the use of Batten Beam Slabs, or BBS. BBS is a type of beam reinforcement that uses steel plates or bars to strengthen the beam. The steel plates or bars are placed in the beam so that they are perpendicular to the beam’s length. This type of reinforcement is often used for beams that are subject to high loads, such as beams in bridges or buildings. BBS is an effective way to increase the strength of a beam without increasing its weight.
Types of Reinforcement ( Rebar) Used in Beam
- There are a variety of types of reinforcement used in concrete beams
- The most common type is rebar, which is made of steel
- Rebars come in a variety of sizes and grades, and can be either smooth or deformed
- They are often used in conjunction with other reinforcement, such as wire mesh or fiber reinforcement.
BBS (Bar Bending Schedule) of Beam
- A bar bending schedule is a table that lists the various lengths of steel reinforcement bars (rebar) that are needed to build a reinforced concrete structure
- It is prepared prior to the start of the construction and is used as a guide during the bending and cutting of the rebar
- The table lists the type, diameter, and quantity of rebar needed for each section of the structure
- It also includes the bend diameter, number of bends, and length of each steel bar
- This information is used to calculate the weight of the rebar, which is needed to determine the amount of concrete required to fill the voids
- The bar bending schedule is an important tool for the reinforced concrete contractor, as it ensures that the correct amount and type of rebar is used in the construction.
How to Calculate Cutting Length of Main Bar in BBS of Beam
- There are two ways to calculate the cutting length of the main bar in a beam:
- Using the Manufacturing Length
- This method is used when the total length of the beam is known
- The cutting length of the main bar is equal to the total length of the beam minus the sum of the lengths of all the other bars in the beam.
- Using the Building Length
- This method is used when the length of the building is known
- The cutting length of the main bar is equal to the length of the building minus the sum of the lengths of all the other bars in the beam.
Conclusion
It is estimated that the use of BBS can save about 30% of the steel quantity used in construction works. This is because the steel beams are better supported and hence require lesser steel to achieve the same strength. BBS also reduces the construction time as well as the overall cost of the project.

What is BBS, and how does it differ from other types of beam reinforcement?
BBS, or Batten Beam Slabs, is a type of beam reinforcement that uses steel plates or bars to strengthen the beam. The steel plates or bars are placed in the beam so that they are perpendicular to the beam’s length. This type of reinforcement is often used for beams that are subject to high loads, such as beams in bridges or buildings.
