What is bar bending?
Bar bending is the manufacture and bending of the steel reinforcing bars and beams, also known as rebar, used as reinforcement in concrete construction. Bar bending has a variety of different scientific measurements associated with it, often referred to as the bar bending schedule.
What is the format of BBS?
Bar Bending Schedule (BBS) is basically the representation of bend shapes and cut length of bars as per structure drawings. BBS is prepared from construction drawings. For each member separate BBS is prepared because bars are bended in various shapes depending on the shape of member.
What is LD in BBS?
Ld – Development Length which is equal to 40d. d – Diameter of Bar. So D = height of the bend bar (refer the image) “D” = Slab Thickness – (2 x clear cover) – (diameter of bar)
