Terzaghi (1943) developed a rational bearing capacity equation for strip footing, by assuming the bearing capacity failure of the foundation in general shear mode. Terzaghi's bearing equation is given by:

q_{u}= CN_{c}+ Î³_{1}D_{f}N_{q}+ 0.5BÎ³_{2}N_{Î³}

- q
_{u}= Ultimate Bearing Capacity of the soil - C= Cohesion
- Î³
_{1},Î³_{2}= Unit weight of the soil above and below the footing level - N
_{c},N_{q},N_{Î³}= Bearing capacity factors that are a function of friction angle - Df= Depth of the foundation below the ground level
- B = Width or diameter of the footing
- L= length of the footing

Square, Rectangular, and Circular Strip Footings |

Terzaghi modified the above bearing capacity equation by introducing shape factors for different shapes of the foundation. Then for

q_{u}= 1.3CN_{c}+ Î³D_{f}N_{q}+ 0.4BÎ³N_{Î³}

q_{u}= 1.3CN_{c}+ Î³D_{f}N_{q}+ 0.3BÎ³N_{Î³}

The values of **N**_{c}, **N**_{q}, and **N**_{Î³}, also change to reduced values that are obtained from Terzaghi's bearing capacity factors for the general shear failure graph, where the bearing capacity factors corresponding to reduced Ð¤ i.e, 0.67tanÐ¤, must be determined.

Then the bearing capacity for:

When the soil is cohesionless, the cohesion factor c = 0; If c =0; the bearing capacity factor Nc = 0; Then the equations for qu can be modified accordingly.

If the soil is cohesive, then the angle of frictional resistance, Ð¤ = 0; then the bearing capacity factors from the graph above, NÎ³ = 0; Nq= 1; and Nc = 5.7; Based on which the qu equation is determined.
