bearingPressure: Bearing Pressure

In geotech: Geotechnical Engineering

Description

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

Usage

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)
