NOTE: Stationary live loads tabulated above are based on a modulus of subgrade
reaction (k) of 100 lb/in3. Maximum allowable stationary live loads for other
moduli of subgrade reaction will be computed by multiplying the
above--tabulated loads by a constant factor. Constants for other subgrade
moduli are tabulated below.

For other modulus of subgrade reaction values, the constant values may be
found from the expression
