Two cables will lift an 18.500-meter-long prestressed pile weighing 3.806 kN/m. 1. Where should each cable be located in relation to the pile ends such that the greatest absolute value of the bending moment in the pile is as modest as possible? 2. At what distance from the pile ends should each cable be placed such that the pile's maximum absolute shear value is as modest as possible? 3. If a cable is placed 3.001 m from one end of the pile while the other end is on the ground, the pile will be lifted. Calculate the pile's maximum developed moment.

Calculation of Settlement

The vertical displacement of the structural foundation due to the loading from the superstructure is known as settlement. It is due to the reduction of air voids present in the soil. The amount of vertical displacement depends on the bearing capacity of the soil on which the foundation is laid. The effect of the settlement depends on the magnitude of settlement, uniformity, and the structural design of the structure. The maximum allowable settlement for residential and office buildings should be less than 18 mm, for industrial buildings, it is 38 mm and for commercial buildings, it is 25 mm.

A 16 in diameter, 75 ft long drilled displacement pile is made of grout with f'c = 5,000 lb/in2. A steel ratio of 0.04 is to be used in the upper 30 ft, and a steel ratio of 0.001 for the remainder of the pile. Compute the modulus of elasticity for the upper and lower portions of this pile.
-- Pile in Sand (friction and end bearing) Make calculations to determine the Allowable Load for a 14-inch square precast concrete pile that is driven into a dense medium to fine sand deposit with = 36 deg. and y = 125 pcf. The pile is driven to 85 ft. depth, and there is still 40 ft. of sand below the pile tip. Groundwater is 6 ft. below ground surface. You are to assume that a static pile load test will be performed on one representative pile for this project. Use the limiting depth and limiting pressure approaches for end bearing and for side friction. State the K and 8 values you use, and justify.
I need detailed explanation to solve the exercise below. There are some formulas and hints, I also added some tables from the book.Meyerhof's method, Coyle and Castello's method and Vesic's method were already solved.
A square prestressed concrete pile with a 14 inch side is to be driven to the necessary depth. It needs to be able to support 105 kips. It has been determined that the point resistance qp is 120 ksf and the side friction fs is 450 psf. Use formula 12.2 (see attached image) to estimate how long the pile needs to be with a factor of safety of at least 2.5. Round your answer to a multiple of 5 feet. Use L as a variable to calculate the load in formula 12.2. L can be obtained from this equation.
Determine the amount of axial shortening that the friction pile undergoes in service. Assume that the surface (or “skin”) friction f (force/lenth2) varies as shown and that E and A are constant.
