Module 05
Shape, depth and inclination
The corrections that turn a strip-footing equation into a real foundation.
What this module covers
- Explain why a square footing carries more pressure than a strip of the same width
- Apply shape and depth factors, and say when each is worth claiming
- Explain why an inclined load is more damaging than its vertical component alone
- Recognise which corrections are conservative to ignore and which are not
Lessons

2 questions
Question 1
An uncorrected capacity of 1056 kPa becomes 1290 kPa once shape and depth factors are applied. What is the percentage gain, to the nearest whole number?
Question 2
For a rectangular footing 2 m by 5 m, what is B in the bearing capacity equation?
