Multiple Load Footing is a simple and straightforward program for the fast and accurate design of strip footings (e.g., combined, strap, trapezoidal, rectangular, etc.) and is best suited for the design of footings that support more than one collinear column (columns that lie on the same line).
Such footings are all but impossible to solve with closed form solutions, so Multiple Load Footing uses a Finite Elements solution based on a Winkler foundation to model the soil.
