Vesic
This solution is based on the theory of A. S. Vesic. The calculation is the same as for standard approach, except the following coefficients:
bearing capacity factors: | |
| |
shape factors: | |
| |
| |
| |
depth factors: | |
for: d/b ≤ 1 |
|
| |
| |
for: d/b > 1 |
|
| |
| |
inclination factors: | |
for: φ = 0° |
|
for: φ ≠ 0° |
|

where: | d | - | depth of the footing bottom |
b | - | width of foundation | |
l | - | length of foundation | |
φ | - | angle of internal friction of soil | |
c | - | cohesion of soil | |
δ | - | angle of deviation of the resultant force from the vertical direction | |
H | - | horizontal component of resultant load | |
V | - | vertical component of resultant load |
