Question Description

solve the 4 problems in the attached PDF file

Take Coduto worked example problem 16.1 soil profile with 14 m long pile. Estimate 1) through 4) for driven pile options:

1) Nominal tip resitance, kPa
2) Nominal tip bearing load, KN
3) Total skin friction, KN
4) Allowable load carrying cpacity, KN, with a FOS of 3

Pile options are: (a) 600 mm or 24-inch diamter cast-in-steel-shell (CISS) pile, (b) 305 mm or 12-inch square prestressed concrete pile, and (c) 14x89 steel H-pile with sectional property as shown below:


Do same tasks as in Problem #1 (with items 1 through 4 above in English units) for driven pile options (a) through (c), but use the information below:
Take Coduto worked example problem 16.2 soil profile with 60 feet long pile.


Take Coduto worked example problem 15.1 soil profile with 19 m long pile and a 400 mm (16-inch) diameter drilled shaft Estimate 1) through 4)

1) Nominal tip resitance, kPa
2) Nominal tip bearing load, KN
3) Total skin friction, KN
4) Allowable load carrying cpacity, KN, with a FOS of 3


Take Coduto worked example problem 15.4 soil profile and a 24-inch diameter drilled shaft Estimate Pile length required in feet to achieve an allowable skin friciton of 250 kips, with a FS of 2
