Notes: For SI: 1 inch = 25.4 mm, 1 kip = 4.448 kN, 1 kip∙in = 113 N∙m. 1. Refer to Section 4.1.3 of ICC-ES ESR-2794 for descriptions of fixed condition, pinned condition, soft soil, and firm soil. 2. Strength ratings include allowance for corrosion of zinc-coated new construction pile caps over a 50-year service life and presume the supported
structure is braced in accordance with IBC Section 1810.2.2. 3. Capacities apply to the specific pile cap and pile models listed.
4. The fixed end condition requires that the foundation itself be fixed and that the pile and pile cap be embedded in the foundation with adequate concrete cover and reinforcing to resist 56.4 kip∙in, 116 kip∙in, 71.66 kip∙in, 138.3 kip∙in, 138.3 kip∙in, and 263.72 kip∙in nominal bending moment for SS5, SS175, RS2875 (including RS2875.203 and RS2875.276), RS3500, RS3500/SS175 combo, and RS4500 pile models, respectively. The center of the shaft must be at least 6 inches away from the end/corner of the concrete footing. 5. See Section 4.1.2 of ICC-ES ESR-2794 for applicable limit states that must be evaluated by a registered design professional. 6. Refer to the specified compressive strength of concrete at 28 days [minimum of 24 MPa is required under ADIBC Appendix L, Section 5.5.1]. 7. Values in brackets [ ] are for use in Seismic Design Categories D, E, and F. 8. The concrete footing design and reinforcement design, including the concrete thickness above the new construction pile cap, must be determined by a registered design professional. 9. (G): The cap is available as galvanized and nongalvanized (bare steel). Catalog items with “G” suffix are galvanized and without “G” are bare steel.
