Figure 10.10. Eccentric pad footing on dry sand

Example 10.2 Eccentric pad footing on dry sand Verification of strength (limit state GEO)

Design situation

Owing to an error on site, the pad footing from the previous design example is out-of-position on plan, such that the imposed actions act at distances eg = 75mm and e| = 100mm from the centre of the footing.

Design Approach 1

Geometry

Eccentricity of total vertical action:

(VGk + YQVQk)x eB (72.4^ e'g =-7—--—\--—= mm'

Load is within middle-third of base if e'B < — = 250 mm

Eccentricity of total vertical action:
