For a 45° cranked bar in a beam, the extra length due to the crank is calculated from the inclined portion.

For a crank over a vertical distance
Inclined length=d/sin45°
=1.414d
The corresponding horizontal projection is:
dcot45°=d
Hence, extra length for one crank:
2(1.414d-d)=0.828d
Therefore, for a beam of effective length (L):
Length of cranked bar=L+0.828d
