Bar Bending is a process for the development of bars in different shapes as required by the particular reinforced concrete work object. Stirrups are utilized to oppose horizontal shear pressure and diagonal tension stress worry in RCC structure. Therefore, the stirrups help prevent the buckling failure of the legs.

Specific criteria to be followed in the planning of the BBS:

• For each structural component, e.g. beam, column, etc., the bars should be grouped together.
• The bars should be marked on the ground in a building structure.
• The schedules as separate A4 sheets and not as part of extensive reinforcement plans should be given for cutting and bending purposes.
• the size of the counter and the form of the bar.
• Bars should be specified in numerical order in the schedule.
• It is appropriate to refer to a particular group or collection of bars in a given width, volume, shape, and type of work only in the references to a bar mark on the label attached to a bundle of bars.
• This is imprescindible as a reference to a bar mark may then point to a bar category. This also improves the control of the type and number of bars necessary to carry out certain work by steel fixers and employees.

The Bar Bending System shall be used in the following:

• Detailer.
• The individual checking the drawing a contractual worker who requests the support.
• The association is answerable for creating the fabrication.
• Steel fixer.
• A representative of works or another assessor.
• The amount surveyor.

The amount surveyor is liable for the estimation and costing tasks of an undertaking. This sort of looking over requests a significant level of accuracy. Bar Bending Schedule encourages the amount surveyor to merge the number of bars expected of each bar type.

This prompts an estimation of the amount of steel, which means the cost prerequisites for steelwork. Henceforth, BBS is utilized by the contractual worker who requests the fortifications also. The unit cost of steel is charged by the weight of steel obtained.

Agent of works and different examiners allude to the BBS to ensure that the fortification work in the site is pair with the structure necessities according to drawings. It is utilized as a casing of reference by the steel fixers firsthand. They can without much of a stretch make note of the number and sort of rebar required for a basic unit.

Fundamentally, Bar Bending Schedule subsumes all important data on fortifications, utilized by experts at different phases of the development procedure, directly from acquisition to wrap up.

How can a BBS be Prepared?

• Bar number.
• Bar shape.
• Diameter.
• Spacing.
• Length of a bar.
• Cutting Length.
• The number of bars.
