The settlement of a foundation can be divided into two major categories:
A- Elastic or immediate settlement
B- Consolidation settlement

For the calculation of foundation settlement, it is required to determine the vertical stress increase in the soil mass due to the load applied on the foundation.
This chapter is divided into the following three parts:
1. Procedure for calculation of vertical stress increase
2. Elastic settlement calculation
3. Consolidation settlement calculation
