Difference Between Lap Length and Development Length

What is Lap Length?

  • Lap Length is also required when the bar diameterΒ has to be changed along the length (as is sometimes done in columns).Branding

  • Using proper splicing techniques.
  • Keeping these lapping locations away from sections with high flexural/shear stresses. and
  • Staggering the locations of splicing at the individual bars of a group (as typically in a column).

  • Increasing the length of the lap length (In lap splices and lap welding)
  • Using spirals or closely-spaced stirrups around the length of the stirrups.

Type of Lapping Method:

  • The lapping of bars (lap splice)
  • Welding of bars (welded splice)
  • Mechanical connection.

SR.NO.DEVELOPMENT LENGTHLAP LENGTH
1Length of reinforcement bar required to transfer load or stress developed in a reinforcement bar into the concrete.Length of reinforcement bar required to completely transfer load or stress from one bar to another bar
2It is denoted by LdIt minuteness the continuity in the structure
3It is always provided at the end of beam, column, or slabIt is provided when the length of bars ends.
4It is also useful for providing grip & support & doesn't allow slippingIt is transferred to continuity and also transfers stees from one bar to another bar.
5This is bound between concrete and reinforcement.This is a bond between reinforcement and reinforcement.
