Where is the lapping zone in Beams, Columns and Slab?

Question

Accepted Answer

The lapping zone in beams, columns, and slabs is the area where reinforcement bars overlap to ensure structural integrity.

Lapping zone is typically located at the ends of beams, columns, and slabs.
It is necessary to provide sufficient overlap of reinforcement bars to transfer loads effectively.
The length of the lapping zone depends on the design requirements and the diameter of the reinforcement bars.
Lapping helps in maintaining continuity of reinforcement and prevents structural failure.
For example, in beams, the lapping zone is usually at the support or near the mid-span.
In columns, the lapping zone is commonly found at the bottom near the footing or at the top near the beam connection.
In slabs, the lapping zone is often at the edges or at the junctions with beams or columns.

Accepted Answer

In Beams it's L/2 at top bars and L/3 at bottom bars... In columns it's at the middle with alternate lapping and In slab it's L/2
