Transverse Flexure in Continuous Footings
The required flexural capacity for a section parallel to the footing's major axis is calculated by defining a width effective to each column or wall as:
For columns away from the footing ends: w/2 + 3d/4 on either side of the column centerline
For columns at the ends of the footing: w/2 + c
The effective width is taken as the sum of the minimum values of the equations above for either side of the column.

The width effective to each column and/or wall along the footing then serves as the basis for the sections for which transverse flexure is evaluated along the footing. This is reflected in the RAM Foundation continuous footing view/update dialogue as segment numbers (see Figure below).
- Overhand Length:
- Total Force on Section:
- Moment Capacity:
The process is repeated for all columns and all the regions between columns.
