PREPARATION OF BAR BENDING SCHEDULE

• Schedule of bars (or bar bending schedule) is a
  list of reinforcement bars, with regard to a
  known RCC work item, and is offered in a tabular
  format for easy visual reference. This table sums
  up all the required specifics of bars as
  diameter, length of each bent, a total length of
  each bar, a shape of bending straight portions,
  number of each type of bar and angles of bending.
  This statistics is a great benefit for preparing
  an estimate of quantities.
• Figure 1 depicts the shape and proportions of
  hooks and bends in the reinforcement bars these
  have adhered to the standard proportions
• Length of one hook (4d) (4d d) where,
  (4d d) denotes to the curved portion 9d.
• The additional length (la) that is presented in
  the simple, straight end-to-end length of a
  reinforcement bar due to being bent up at say 30o
  to 60o, but it is generally 45o) l1 l2 la
• Where,
