A solid steel pile (E = 200 GPa) with uniform diameter of 100 mm is driven into a soil layer and placed on top of a rigid bedrock. If the pile is subjected to a vertical force YS: KN and the soil provides uniform frictional resistance of 2 kN/m. Determine the displacement at A'sthe top of the pile. kN A Ground surface Soil 2 m Soil 20 20 Rigid bedrock (Hint: rigid bedrock does not deform) kN/m Steel pile KN/m

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.
