Important of Lapping Length in Reinforcement Bar

Lapping Length in Reinforcement Bar

Lapping length in the reinforcement bar is also described as an overlapping length of the bar so they act as a single bar

The length of reinforcement is restricted to (12 meters or 40 feet) and the height or length of the building is more so there is an option like
Because if we make a more than this length, then we have to face some trouble given below
  • Transportation is difficult
  • To work with heavy steel is impossible for labor
  • It May be possible to change in design position of Reber is defer from the correct position

What is the solution to the sort length reinforcement bar?

  1. Lapping of bar
  2. Welding of bar
  3. Mechanical Joint 

So for joining two bars to perform as a single bar IS CODE give some recommendation for the lapping length required to give the best bond and act line single unit.

Normally lapping length of the bar is 50D or 54D ( D=diameter of the bar)
