Development length is the length overlap of bars tied to
extend the reinforcement length. is about 50 times the dia
of bar is consider to safe.
Anchorage length- this is the additional length of bar
recquired ti insert in another at the junction. For example-
Main bar of the beam in column at beam column junction.
this length is simiilar to the lap length.
Development Length : Is a length of bar or
reinforcement rod is required to transfer the load to
another bar safely and not affecting to the member which is
in it. 49 times of bar is compression and 46 times is in
tension. But in construction 50 times takes of bar diameter.
Anchorage Length : Required distance to transfer
load and which is depends up on member competence i.e. type
of materials used and bearing strength and type of grout
which is in it.
