This section discusses the assumptions made within RAM Foundation for configurations in which multiple foundations intersect at a single point.

When calculating structural foundation capacities (i.e., footing flexure, one-way shear, two-way shear, etc.), RAM Foundation assumes no interaction occurs between intersecting footings. Thus, the procedure for the sizing of the footing and reinforcing is the same whether or not a given footing intersects another. The question RAM Foundation seeks to answer in such configurations is how the loads coming from the supported column or wall should be divided among the supporting footings.

A Mat foundation assignment is available in RAM Modeler. However, foundations with this assignment must be processed in RAM Concept and no design information will be available for Mat foundations within RAM Foundation. The plan geometry of all mat foundations is drawn in RAM Foundation purely for reference.
