please use the hand writing notes I provided since that is the method they request on how to solve the problem. thank you.

14.6 An industrial building is to be supported on a series of 14-in square prestressed concrete piles which will be driven 45 ft into the following soil profile: Friction Angle b (deg) Unit Weight Depth (ft) Relative Density D Soil Classification Non (Ib/ft) 0-10.0 33 40% 12 100 10.016.5 31 507 Silty sand (SM) Sandy silt (ML) Fine to medium sand (SW) Well-graded sand (SW) 110 16.535.0 35 627 35.0 65.0 67 68 WE I The groundwater table is at a depth of 15 ft and all of the strata may be assumed to be nor- mally consolidated. These piles have been designed without the benefit of any onsite static load tests, dynamic tests, or indicator piles, but a wave equation analysis has been performed. Compute the allowable downward and upward load capacities of each pile. 2 = 10/2=8Ft 22=13.25 Zz = 25.75 24 = 45 B = 1.5-0.135 z = 1.2 B2 = hool B3 = 0.81 By = 0.59 OD, = YD-Up = 100 C) = loo 02 = 10 (6.5) -62.466.8) = 244.4 0123= 996.9 o'24 = 870.8 & fs. = Bok = 1200 fs2=3238.8 fs3=807.5 Isy= 513.8 Asi = C D = 14 (^x 10) = 36.65 12 As2=23.82 Asa=69.81 As y= 109.96 ft PS3=54756.58 Ps. = Es As = 43980 Ps2=77148.22 Ps4=56497. 45 Pult = EPS + Pe - w Po = Et At Et = Pile & sand - BCY) CN*) + O2D ENTE) At= B 1.37 ft Es = Bo Jock + P Noo 2
