Abstract:

Both the Florida Department of Transportation

(FDOT) and the Federal Highway Administration

(FHWA) specify use of fixed resistance factors (φ)

for Load and Resistance Factored Design (LRFD) of

deep foundations, depending on design approach

and redundancy of the foundation. A specified φ

for a design requires a certain level of reliability, a

function of uncertainties associated with material

properties, construction methods, and selected

design approach. Subsurface spatial variability is

a significant uncertainty; for instance, Florida’s

coastal terrain presents stiff challenges to

quantifying variability of soil/rock properties.
