SPS 362.1810 Note 1. Washington State Department of Transportation formula:
Rn = 6.6Feff WH ln(10N)
SPS 362.1810 Note Where:
SPS 362.1810 Note Rn is the ultimate axial compression capacity in kips.
SPS 362.1810 Note Feff is an efficiency factor based on hammer and pile type.
SPS 362.1810 Note W is the hammer weight in kips.
SPS 362.1810 Note H is the drop height of the hammer in feet.
SPS 362.1810 Note N is the average penetration resistance at the end of driving, in blows per inch.
SPS 362.1810 Note Acceptable Feff values are:
SPS 362.1810 Note 0.55 for all pile types driven with an air or steam hammer.
SPS 362.1810 Note 0.37 for open-ended diesel hammers for concrete and timber piles.
SPS 362.1810 Note 0.47 for open-ended diesel hammers for steel piles.
SPS 362.1810 Note 0.35 for closed-ended diesel hammers for all pile types.
SPS 362.1810 Note 2. Corrected FHWA-Modified Gates Equation:
Ru = [(1.75)((e Er)0.5) (log(10 Nb))-100] (Fo ) (Fs) (F p) (Fh)
SPS 362.1810 Note Where:
SPS 362.1810 Note Ru is the ultimate axial compression capacity in kips.
SPS 362.1810 Note e is the hammer efficiency.
SPS 362.1810 Note Er is the hammer energy in foot-pounds.
SPS 362.1810 Note Nb is the final penetration resistance in blows per inch.

SPS 362.1810 Note Fp is a correction factor for pile type.
SPS 362.1810 Note Fh is a correction factor for hammer type.
SPS 362.1810 Note Acceptable hammer-efficiency values are:
SPS 362.1810 Note 0.75 for drop hammers.
SPS 362.1810 Note 0.85 for other hammers, or an efficiency recommended by the hammer manufacturer.
SPS 362.1810 Note Acceptable correction factors are:
SPS 362.1810 Note Overall Fo: 0.94.
SPS 362.1810 Note Soil Fs: 1.00 for mixed soil profile.
SPS 362.1810 Note 0.87 for sandy soil profile.

SPS 362.1810 Note 1.01 for air or steam double-acting.
SPS 362.1810 Note 1.00 for hydraulic.
SPS 362.1810 Note If at least 1 static load test is performed to field-check the penetration resistance criteria calculated by the above dynamic formulas, a minimum safety factor of 2.5 must be applied to the ultimate axial compression capacity calculated by the dynamic formula to determine the allowable pile load. If only dynamic testing (including signal matching) is performed to field-check the penetration resistance criteria determined by the dynamic formula, a minimum safety factor of 2.75 must be applied to the ultimate axial compression capacity calculated by the dynamic formula to determine the allowable pile load. If no field testing is performed to check the penetration resistance criteria calculated by the dynamic formula, a minimum safety factor of 3.0 must be applied to the ultimate axial compression capacity calculated by the dynamic formula to determine the allowable pile load.
SPS 362.1810 Note The above formulas are predicated on the following three conditions: (1) static load testing and/or dynamic testing being performed on pile(s) driven in uniform site soil conditions, (2) test pile(s) being driven with the same hammer and cushion used for installation of production piles, and (3) test pile(s) being of the same type and section used for production piles. If any of the three conditions is not met, additional field testing is required. With static load testing and/or dynamic testing, penetration resistance criteria calculated by the dynamic formula must be modified as appropriate based on the results of the field testing. A site must be defined as a project site, or a portion of it, where subsurface conditions can be characterized as geologically similar in terms of subsurface stratigraphy, including the sequence, thickness, geologic history, engineering properties and groundwater aspects.

SPS 362.1810(7)(a) (a) Where deep foundations are installed through subsiding fills or other subsiding strata and derive support from underlying firmer materials, consideration shall be given to the downward drag load that may be imposed on the deep foundations by the subsiding upper strata.
SPS 362.1810(7)(b) (b) Where the influence of subsiding fills is considered as imposing loads on the deep foundation, the allowable stresses specified in this chapter are permitted to be increased where satisfactory substantiating data are submitted.

SPS 362.1810(8) (8)Design cracking moment. Substitute the following equation for IBC equation 18-11: jMn = 3(f'c)0.5( Sm).
SPS 362.1810(9) (9)Driven timber piles. Substitute the following wording for the requirements in IBC section 1810.4.1.5: Any sudden decrease in driving resistance of an end-supported timber pile shall be investigated with regard to the possibility of damage.
