Side load bracket plate must be fully engaged with bottom <br /> of concrete foundation Only localized limit states such as mechanical strength of steel components and concrete hearing have been <br /> evaluated. <br /> 2Lateral load capacity is based on lateral load tests performed in firm clay soil per Section 4.1.1 of this report.For any other soil condition,the <br /> lateral capacity of the pile must be determined by a registered design professional. The bracket must be installed with minimum embedment <br /> of 3 inches when measured from the bottom of the concrete foundation to the bottom of the bracket plate. Minimum width of footing must be <br /> 12 inches. <br /> 'The capacities listed in Table 1 assume the structure is sidesway braced per 2018,2015,2012 and 2009 IBC Section 1810.2.2 and 2006 IBC <br /> Section 1808.2.5. <br /> 4Tieback assemblies must be installed in accordance with Section 4.2.5 of this report. Only localized limit states such as mechanical strength <br /> of steel components and concrete bearing have been evaluated. The tieback assembly must be installed to support a minimum 6-inch-thick <br /> concrete wall. Two through bolts are required for connection between bracket sleeve and helical shaft.Bolts must be 3/4-inch diameter <br /> complying with ASTM A325 and installed snug-tight with threads excluded. <br /> 6The tabulated values are based on installation with normal-weight concrete having a minimum compressive strength of 2500 psi(17.23 MPa). <br /> 6The lateral load capacity of the side-load brackets must be designed by a registered design professional in accordance with Chapter 18 of the <br /> IBC. <br /> N/A=not applicable. <br /> TABLE 2-MECHANICAL PROPERTIES AFTER CORROSION LOSS IN STEEL THICKNESS OF <br /> 2.875-INCH-,3.5-INCH-,AND 4.5-PICH-DIAMETER HELICAL SHAFTS' <br /> SHAFT DIAMETER <br /> MECHANICAL PROPERTIES (inch) <br /> 2.875 I 3.5 I 4.5 <br /> Steel Yield Strength,F2(ksi) 65 65 65 <br /> Steel Ultimate Strength,F„(ksi) 80 76 76 <br /> Modulus of Elasticity,E(ksi) 29,000 29,000 29,000 <br /> Nominal Wall Thickness(inch) 0.217 0.254 0.237 <br /> Design Wall Thickness(inch) 0.1758 0.2102 0.1944 <br /> Outside Diameter(inch) 2.8490 3.4740 4.474 <br /> Inside Diameter(inch) 2.4974 3.0536 4.085 <br /> Cross Sectional Area(inch2) 1.48 2.16 2.61 <br /> Moment of Inertia,I(inch') 1.32 2.88 6.00 <br /> Radius of Gyration,r(inch) 0.95 1.16 1.51 <br /> Section Modulus,S(inch') 0.93 1.66 2.68 <br /> Plastic Section Modulus,Z(inch4) 1.26 I 2.24 I 3.56 <br /> For SI:1 inch=25.4 mm; 1 ksi=6.89 MPa, 1 ft-lbf=1.36 N-m;1 lbf=4.45 N. <br /> 'Dimensional properties are based on powder coated steel losing 0.026-inch steel thickness as indicated in Section 3.9 of AC358 for a 50-year <br /> service life. <br />
