WebAccording to the IS code for calculating the required development length by substituting the stress value $\sigma_s$ equal to $0.87f_y$. As it is the full strength that a rod can bear. For more than this stress rod will break. … WebLap Length As Per IS 456 Generally, development length is 41d where d is the diameter of the bar. For direct tension, the lap length should be 2 Ld or 30d whichever is greater is considered. In this case, the straight length of the lapping bar shall not be less than 15d or 20cm.

Lapping should not be done at the midpoint of the beam, but either at the intersection of the column and the beam, or L/4 length from the casting face of the column. The stirrups should be mounted closely to the lapping zone.
WebThe development length can be defined as the length of the bar required for transferring the stress into the concrete. In other words, development length is the quantity of the rebar length that is actually required to be enclosed into the concrete to make the desired bond strength between two materials and furthermore to produce required ...
