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
	R_d	-	bearing capacity of foundation soil
	SF_v	-	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
	A_ef	-	effective area of the foundation

The bearing capacity R_d determined from the CPTs:

The bearing capacity R_d determined from the SPTs:

The bearing capacity R_d determined from the PMTs:
