Chapter 12, Problem 12.24P
Solve Problem 12.23 using the method of Broms. Assume that the pile is flexible and free headed. Let the soil unit weight, γ = 16 kN/m3; the soil friction angle, ϕ′ = 30°; and the yield stress of the pile material. FY = 21 MN/m2.
12.23 A 30 m long concrete pile is 305 mm × 305 mm in cross section and is fully embedded in a sand dcposit. If nh = 9200 kN/m2, the moment at ground level Mg = 0, the allowable displacement of pile head = 12 mm; Ep = 21 × 106 kN/m2, and FY(pile) = 21,000 kN/m2, calculate the allowable lateral load, Qg, at the ground level. Use the elastic solution method.
