# Bearing Pressure

### Description

This function computes the gross bearing pressure that a soil would experience due to a foundation.

### Usage

1 | ```
bearingPressure(P, B, L, D, Dw, metric, gammaW = NA, gammaC = NA)
``` |

### Arguments

`P` |
Vertical gross column load (lb or kN) |

`B` |
foundation width (ft or m) |

`L` |
foundation length (ft or m) |

`D` |
Depth of foundation (ft or m) |

`Dw` |
Depth of groundwater table below foundation base (ft or m) |

`metric` |
logical variable: TRUE (for metric units) or FALSE (for English units) |

`gammaW` |
unit weight of water (default = 62.4 pcf for English units; 9.81 kN/m^3 for metric units) |

`gammaC` |
unit weight of concrete (default = 150 pcf for English units; 23.6 kN/m^3 for metric units) |

### Details

Either SI or English units can be used, but must stay consistent.

When specifying the length and width, L should be the longer of the two lengths.

For a continuous (strip) foundation, specify L = 1 and specify P as the load per unit length.

When the groundwater table is deep or unknown, set Dw >= D.

### Value

Gross bearing pressure of footing (psf or kPa)
