Transmission And Substation Foundations - Technical Design Manual (TD06088E)

2. Assumptions a. Boring is representative of the site 1. Water table depth: 0 ft. b. Loads given: i. 10kip Comp ii. 80kip Tension iii. Shear

1. Transverse: 9.5kip 2. Longitudinal 4kip

iv. Moment:

1. Longitudinal: 150kip ft. c. Piles are installed at ground level d. Torque to Capacity Ratio: 10:1 d. Head Condition: Fixed e. Axial FS: 2.0 f. Amount of Lateral deflection acceptable at working loads: 0.2 3. Notes i. May reach installation torque before reaching minimum embedment. Adhere to minimum embedment requirements ii. Ensure final torque is greater than required installation torque at given depth iii. Maximum torque for SS175 is 10,500 ft-lbs. Do not Overtorque! (Torque capacities can be found in the Drawings and Ratings section)
