1. This example explores a column footing in a homogeneous clay layer. Find the ultimate bearing capacity, allowable bearing capacity and allowable load of a 1.2 m x 1.2 m square footing placed in a clay layer. The density of the soil is found to be 17.7 kN/m² and the cohesion was found to be 20 kPa. Clay d=1.2m y= 17.7kN/m? C- 20 kPa factor of safety (F.O.S.) = 3.0

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.
