BBS (Advance Bar Bending Schedule)
Bar bending schedule or schedule of bars is a tabular representation of reinforcement bar. It is generally represented for each type of R.C.C work.
With the help of bar bending schedule the requirement of different length and sizes of bars may be known and can be arranged and bent-up during the time of construction.
Bar bending schedule generally describes the particulars of bars, shape of bending with sketches and total length and weight of the bars along with their numbers.
Bar bending schedule is generally prepared while estimating a R.C.C work or structure.
From 1950 to 2019 lots of modifications and enhancements happening in our world. In 1950, three-storeyed buildings are high rise buildings now we are constructing a building with 200 floors+. There is a massive growth in the construction industry. Due to the vast increase in world population demands increased facilities, more need for space and more construction.
Father of Estimation B.N. Datta has given certain recommendations for the usage of steel in different components of buildings. But, he didn’t mention any values if we use more bars in a single structural member.
Introductory phase covers, Reinforcement, its necessity.
