The market standard for rebar length is 12m, and to construct a column spanning upwards anything more than 12m (i.e. 100m), lapping between rebars will be required.
This is because rebar lapping is to allow for a safe transfer of load from one bar to another and retain continuity.
A good practice is to have rebar lapping to be at the middle height of the column. This is because for taller structure, due to lateral forces from wind, moment will be induced at laterally braced zone; every storey. Hence, zero moment would be at the middle height of the column.
An alternative to rebar lapping is by using rebar couplers.
