Width of Footing for Local Shear Failure given Bearing Capacity Factor Formula Elements

Variables
Width of Footing
Width of Footing is the shorter dimension of the footing.
Symbol: B
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Ultimate Bearing Capacity in Soil
Ultimate Bearing Capacity in Soil is defined as the minimum gross pressure intensity at the base of the foundation at which the soil fails in shear.
Symbol: qfc
Measurement: PressureUnit: kPa
Note: Value should be greater than 0.
Cohesion in Soil as Kilopascal
Cohesion in Soil as Kilopascal is the ability of like particles within soil to hold onto each other. It is the shear strength or force that binds together like particles in the structure of a soil.
Symbol: C
Measurement: PressureUnit: kPa
Note: Value should be between 0 to 50.
Bearing Capacity Factor dependent on Cohesion
Bearing Capacity Factor dependent on Cohesion is a constant whose value depends upon the cohesion of soil.
Symbol: Nc
Measurement: NAUnit: Unitless
Note: Value should be greater than 0.
Unit Weight of Soil
Unit Weight of Soil mass is the ratio of the total weight of soil to the total volume of soil.
Symbol: γ
Measurement: Specific WeightUnit: kN/m³
Note: Value should be greater than 0.
Depth of Footing in Soil
Depth of Footing in Soil is the longer dimension of the footing in soil mechanics.
