For combined footings, why do I get a warning rigid entity length to width ratio?
The foundation module uses the provisions of ACI 318 for rigid foundations. The foundation is determined to be rigid by length to width ratio values. The warning acknowledges that this is a flexible foundation. The engineer will need to either change the footing dimensions to be within guidelines OR do some additional checks based on ACI flexible foundation design.
The following equations are used to determine rigid footing classification:
ACI does not give specific guidelines for rigid classification. These equations are taken from
