B1/VM4
The solution is based on NZ standard B1/VM4, where the bearing capacity of foundation soil is given by the formula:
bearing capacity factors: | |
| |
| |
shape factors: | |
| |
depth factors: | |
for d/b ≤ 1: |
|
for d/b > 1: |
|
inclination factors: | |
for φ = 0: | |
where: | d | - | depth of the footing bottom |
b | - | width of foundation | |
l | - | length of foundation | |
c | - | undrained shear strength | |
H | - | horizontal component of resultant load | |
V | - | vertical component of resultant load |
