induced_stress | R Documentation |
Plots the stress distribution under the center of a footing of different shapes.
induced_stress( qs, B, L = NULL, z.end, footing = c("strip", "square", "rectangular", "circular") )
qs |
The stress applied by the footing onto the surface |
B |
The footing's width (in meters) |
L |
The footing's length for a rectangular footing (in meters) |
z.end |
The depth to which calculate the stresses (in meters) |
footing |
Type of footing for which to calculate the stresses (Default is "strip") |
The stresses are calculated using the solutions from Boussinesq. The parameter L
only applies for rectangular footings, otherwise is not considered, thus the default value of NULL
. For rectangular footings the length (L
) can be varied, while for the other footing shapes the width B
can be varied. For circular footings the width is equal to the radius (B=R
)
