The document discusses bar bending schedules, which list the reinforcement bars needed for concrete structures. It provides examples of bar bending schedules for beams, slabs, columns and walls. Details included are member identification, bar type, diameter, length, shape code and bending dimensions. Guidelines are given for accurately measuring and bending bars while ensuring proper cover and avoiding bundled bars. Sample calculations demonstrate how to generate a schedule for a given beam design. Relevant codes and standards are also cited along with websites that provide bar bending schedule software.

M-1 = 4000 + 2 x 228 – 2 x 40 + 2 x (18
x 20)
= 5096
M-2h = 375 – 2 x 40 – 2 x 10 – 2 (15/2) =

M-2h = 375 – 2 x 40 – 2 x 10 – 2 (15/2) =

M-2 = 4000 + 2 x 228 – 2 x 40 + (0.414 x 260) x 2
= 5091
H-1
H-1 = 4000 + 2 x 228 – 2 x 40
= 4376

a = 375 – 2 x 40 – 10 = 285 mm
bb = 228– 2 x 40 – 10 =138 mm
Total length of S-1 = 2 (138 + 285 + 18 x 10) = 1206 mm
