Continuous Footings

A continuous footing may support the following members and member configurations in RAM Foundation:
  • Two or more gravity or lateral columns
  • Two or more lateral columns into which any number of braces frame (at any height along the column span)
  • A single or multiple gravity or lateral walls that lie in the same plane as the footing centerline, within the user specified tolerance
  • Any combination of the above configurations

A single continuous line of individual walls must be completely supported by a continuous footing, as shown in first figure below. An assignment of a continuous footing to only a portion of the walls, as shown in Figure below, is not allowed in RAM Modeler.

Adjacent Walls 1 and 2 Supported by Continuous Footing

(a) Continuous Footing Supporting Wall 1 Only

(b) Continuous Footing Supporting Wall 2 Only at Story n+1

Continuous Footing Assignments Not Allowed by RAM Modeler

For the framing configuration of a wall with columns at each wall end, as shown in first figure below, a continuous footing must be used to support the wall. If spread footings are assigned at each column without a continuous footing assigned along the wall, as shown in Figure below, a warning will be delivered in RAM Foundation and the spread footings will not be able to be designed.
