Notes: For SI: 1 kip = 4.448 kN. 1 Refer to Section 4.1.3 of ESR-2794 for descriptions of fixed condition, pinned condition, and soft 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 and the lead section with which the extension is used will provide sufficient helix capacity to develop the full shaft capacity. 3 Column length to “fixity” of shaft in soil = 10 feet (3 meters).
