Foundations - (1)
- Function
- Evenly transmits load(s) to the ground the foundation rests on (subsoil) safely & eliminate damaging ground movement during construction and throughout the anticipated life of the structure
- Load
- Dead
- Structual
- Wind
- Imposed
- Damaging ground movement
- Frost heave - caused by freezing and expanding water
- Soil movement
- Change in volume of water in ground - when soil wet / dry
- Subsidence
- Trees
- Abstraction from vegetation
- Weather
- Bearing Capacity
- Defined: Maximum Pressure of ground
- Problem: Load exceeds bearing capacity
- Downward movement of foundations occurs
- Solution
- Reduce load carried by foundation
- Increase plan size of foundation to reduce load per unit area
- Soil heave
- Soil shrinkage
