The critical section of finding maximum bending moment for footing under masonry wall is located halfway between the middle and edge of the wall. The maximum bending moment occurs where the load is transferred to the footing and the load is largest, and this typically occurs at the location of maximum leverage, which is halfway between the middle and the edge of the wall.
This is due to the fact that the load is transferred to the footing through the wall and it tends to be more concentrated at the corners, which creates more leverage than in the middle of the wall. By considering this section the designer can ensure that the footing and the foundation is properly designed to resist the expected forces and moments.

The critical section of finding the maximum bending moment for a footing under a masonry wall is located halfway between the middle and the edge of the wall. This location is determined based on the distribution of load from the wall onto the footing.
Here is an explanation of why the critical section is located at this specific location:
1. Load Distribution:
- When a masonry wall is constructed on a footing, it exerts a load onto the footing due to its self-weight and any additional loads acting on the wall.
- The load is distributed over the footing based on the width and thickness of the wall.
- The load distribution is not uniform, and it varies along the length of the footing.
2. Bending Moment:
- The bending moment is the measure of the bending or flexural stress experienced by a structural member, in this case, the footing.
- In the case of a masonry wall on a footing, the maximum bending moment occurs at the critical section where the load distribution is such that it creates the highest bending moment in the footing.
3. Critical Section Location:
- To determine the location of the critical section, we need to consider the load distribution from the wall.
- The load distribution is typically triangular, with the maximum load at the center of the wall and zero load at the edges.
- The maximum bending moment occurs where the load is maximum, which is at the center of the wall.
- However, due to the triangular load distribution, the bending moment also varies linearly from the maximum at the center to zero at the edges.
- Therefore, the critical section is located halfway between the middle and the edge of the wall, where the bending moment is maximum.
In summary, the critical section for finding the maximum bending moment for a footing under a masonry wall is located halfway between the middle and the edge of the wall. This location is determined based on the load distribution from the wall onto the footing, where the bending moment is maximum.
