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") )
Arguments
| 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") |
Value
A stress distribution plot for the desired footing
Details
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)
