Thank you for clarifying the difference Between the D.L. and L.L. for reinforcing bars, but to be clarified for the lapping positions , that it will depend on what is the layer working on for lapping, that's mean if the lapping will be done for the R,bars in tension side , then it should be at the mid center line of the supports while if the lapping is required to the compression side , then it should be at the mid way of the mid span
@monuyadav41265 жыл бұрын
Lapping is done through basically three methods 1 splicing 2 welding 3 anchoring by mechanical means Splicing: never splice steel bars greater than 36 mm due to eccentric effect For direct tension : max of 2Ld or 30d For flexure tension : max of Ld or 30d For compression bar: 24d In no case lapping should be less than ( 15d or 200mm)max

Development length is the length required for the full development of stress in the Steel, and lapping length varies from 50d to 55d from horizontal and for vertical.
