Net Bearing Capacity for Undrained Loading of Cohesive Soils Solution

STEP 0: Pre-Calculation Summary
Formula Used
Net Bearing Capacity = Alpha Footing Factor*Bearing Capacity Factor Nq*Undrained Shear Strength of Soil
qu = αf*Nq*Cu
This formula uses 4 Variables
Variables Used
Net Bearing Capacity - (Measured in Pascal) - Net Bearing Capacity is the maximum net pressure intensity to which the soil at the base of the foundation can be subjected without risk of shear failure.
Alpha Footing Factor - Alpha Footing Factor is a dimensionless coefficient that is used in bearing capacity equations. It modifies the ultimate bearing capacity of the soil.
Bearing Capacity Factor Nq - Bearing Capacity Factor Nq used in a bearing capacity equation that correlates with the angle of internal friction of soil.
Undrained Shear Strength of Soil - (Measured in Pascal) - Undrained Shear Strength of Soil is the shear strength of a soil when it is subjected to rapid loading and does not have enough time to drain.
STEP 1: Convert Input(s) to Base Unit
Alpha Footing Factor: 1.3 --> No Conversion Required
Bearing Capacity Factor Nq: 1.98 --> No Conversion Required
Undrained Shear Strength of Soil: 17 Kilopascal --> 17000 Pascal (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
qu = αf*Nq*Cu --> 1.3*1.98*17000
Evaluating ... ...
qu = 43758
STEP 3: Convert Result to Output's Unit
43758 Pascal -->43.758 Kilopascal (Check conversion ​here)
FINAL ANSWER
43.758 Kilopascal <-- Net Bearing Capacity
(Calculation completed in 00.006 seconds)
