first take clear span dimension.
bottom bar length = clear span+Ld of the bottom bar+2d.
where Ld=development length of the bar
2d = 2 X dia of bottom bar (extra length added for
elongation of bar due to bending).
Same formula is used for the top bar length.
Curtail bar length = Clear span -0.2(clear span)
Stirrups length = (((B+D)-4Cover)+ 10d)*2
Where B = width of beam
D = Depth of Beam
d = dia of bar used for stirrups.
Weigth per Meter length =d*d/162
Where d= dia of bar
