Stress Influence Coefficients
For a Rectangular, Uniformly Distributed Load
You might think this is a joke in this computer age, but it's a "five figure" table for reference.
B = Width (Breadth), and
L = Length of the rectangular load,
z = depth of the point of interest
Enter the table with parameters:
m = B/z and n = L/z
