TABLE $12\mathrm{.}2$ COMMON STEEL PIPE PILE SECTIONS USED IN THE UNITED STATES

The first atimber in the pile devignation is the outside diameter: the second number is the wall thickness.

'The allowable axial load when no moment is present $(F_{a}A)$ is based on $F_a=0\mathrm{.}35f_z$ and $f_y=36\frac{k}{i}{m}^2.$curve b in figure $13\mathrm{.}12$ has been obtained from a static load test on a $60$ ft long pp$18$x$0\mathrm{.}375$ pile, using davissons method compute the ultimate load capacity.
