Bearing capacity analysis
The bearing capacity of the foundation soil can be calculated according to the CPTs, SPTs, or PMTs and verified according to the factor of safety as:
where: | σ | - | extreme contact stress at the footing bottom |
Rd | - | bearing capacity of foundation soil | |
SFv | - | safety factor for vertical bearing capacity (for input use the "Analysis" frame) |
Extreme design contact stress at the footing bottom is given as:
where: | V | - | extreme vertical force |
Aef | - | effective area of the foundation |
The bearing capacity Rd determined from the CPTs:
- "Meyerhof" method
- "Schmertmann" method
- "Skempton" method
The bearing capacity Rd determined from the SPTs:
- "Meyerhof" method
The bearing capacity Rd determined from the PMTs:
