Details For Lap Length In Column, Beam and Slab


  • For beam, usually, 24d is chosen for compression zone and 45d for tensile zone.
  • Lapping should not be arranged at the midpoint of beam rather it should be arranged at the meeting point of column & beam or in L/4 length from the casting face of column.
  • The stirrups should placed narrowly at lapping zone.
  • Lapping of bars should be arranged alternately.
