What is the exact position of lapping in a beam and a column with grade?

Shall give you the golden rules for lapping in Beam-

1.Don't Lap the bars in the mid span

2.Don't lap one bar more than once

3.Stagger the laps in the adjacent bars

Same rules apply for columns -

1.Don't Lap the bars in the mid height

2.Don't lap one bar more than once between the floors.

2.Stagger the laps in the adjacent bars
