Situation 5 - A rectangular pile (0.77 x 0.72 m.) is driven in a clayey soil arrangement composed of two different layers. First layer has a height of 7 m., cohesion of 53 kPa, friction factor of 0.89. Second layer has a height of 8 m., cohesion of 78 kPa, and friction factor of 0.88. (A.) Compute the skin friction resistance in kN. Round off to two decimal

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.
