A computer program written for IBM/360 computer is described that does the optimum design of eccentrically loaded footing as per ACI Code 318-63. The footing may be restricted in dimensions in one or both directions. The program designs a preliminary sized footing based on least area, calculates its cost in dollars, tries six different sizes close to the first size, compares the cost, and chooses the footing with the least cost. It also calculates the quantities of steel and concrete. Results obtained using the computer program are presented and used to show that the footing designed by computer is the optimum footing.
