Question
A 15 m long steel pipe pile of cross section of 0.6 m outside diameter is driven into a sand
deposit. The pile penetration depth in sand deposit is 12 m. The pile is subjected to a lateral
load of 45 kN at a height 3 m above the ground level. Known the information in the figure
below, calculate the pile lateral deflection at the ground level (z = 0) and the pile bending
moments at the depth of 1 m and 2 m below the ground level. Use the elastic solution
method.
