Lap reinforcement is needed because if lap is not given in a steel structure,that portion will be filled only with mass concrete and it will not attain the expected strength,so inorder to prevent that we can provide a lap rod whose length is 50D i.e 50 times the diameter of the rod.
yes, joint measurement for laps should be recorded
40 times diameter
Drill out the edge of the slab and add some dowels....or cut the slab back.
if the bar length is 5o m , what will be the actual length including lap length
when length of reinforcing bar is small and we have to provide longer reinforcement in that case the second bar is provided with proper overlapping with the first bar this overlapping is known as lap length. the straight length of shall not be less than 12mm dia and 200mm length.

Reinforcement designed to resist shear or diagonal tension stresses.

shear reinforcement
The wall was damaged and would need some reinforcement to keep it standing for now.

It depends on the stress/load applied to a beam, but a general rule is to provide a lap where the stress is the least. In a simply supported beam with a uniformly distributed load the best place to position laps would be away from the centre of the beam.
Torsion reinforcement provided at the corner of two way slab to control cracking at corners.
