Preparation of bar_bending_schedule
1. 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:
(a) Length of one hook = (4d) + [(4d+ d)] where, (4d+ d) denotes to the curved portion = 9d.
(b) 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,

Giving different values to respectively), we get different values of la, as shown below:
Figure 2 shows the technique to reach the length of hooks & the total length of a given steel
reinforcement.
