For SI: 1 kip = 4.448 kN. 1 Refer to Section 4.1.3 of ESR-2794 for descriptions of fixed condition, pinned condition, soft & firm soil. 2 Strength ratings are based on a design corrosion level of 50-years and presume the supported structure is braced in accordance with IBC Section 1808.2.5. 3 Column length to “fixity” of shaft in soft soil = 10 feet (3 meters), and 5 feet (1.5 meters).
