What is the lapping location for top and bottom bar of a beam?

Question

Accepted Answer

The lapping location for top and bottom bars of a beam is typically at the mid-span of the beam.

The lapping location is where two reinforcement bars are overlapped and connected to ensure continuity and strength in the beam.
For top bars, the lapping location is usually at the mid-span of the beam, where the bending moment is maximum.
For bottom bars, the lapping location is also at the mid-span of the beam, but it can vary depending on the design and structural requirements.
The lapping length should be sufficient to develop the required bond strength between the bars and avoid any potential failure.
Proper lapping of reinforcement bars is crucial to ensure the structural integrity and load-carrying capacity of the beam.

Accepted Answer

lap is top bar at midspan, and lap in bottom bar at near support.

Accepted Answer

For top bar at beam center, for bottom bar at col Junction or lessthan L/4 dostance from column face
