Using the design values in Problem 9.26, determine the required width of a footing that must
support the following ASD load combinations:
a. Max load combination: P = 200 k,V = 0
Service loads: P = 180 k, V = 0
b. Max load combination: P = 200 k, V = 21 k
Service loads: P = 180 k,V = 0
c. Max load combination: P = 440 k, V = 40 k
Service loads: P = 400 k,V = 0
d. Max load combination: P = 480 k,V = 40 k
Service loads: P = 360 k,V = 0
