Bearing capacity
To calculate the bearing capacity of the foundation various methods can be used:
| • | Hansen's method |
Select this method to determine bearing capacity on loose soils.
| • | Terzaghi's method |
Select this method to determine bearing capacity on loose soils.
| • | Meyerhof's method |
Select this method to determine bearing capacity on loose soils.
| • | Vesic's method |
Select this method to determine bearing capacity on loose soils.
| • | EC-8 Method |
Choosing this option allows the computation of the bearing capacity according to the guidelines of Eurocode 7 (on geotechnical design) and Eurocode 8 (on earthquake).
| • | Terzaghi's method on rock |
Select this method to determine bearing capacity on rock.
| • | Zienkiewicz's method on rock |
Select this method to determine bearing capacity on rock.
The vertical and horizontal bearing capacity are calculated for each design combination.
Through the "Analysis options" command in the "Bearing capacity" computation window the user can select the type of analysis to be performed:
| • | Drained condition: Select this option to calculate the foundation bearing capacity in drained conditions (effective parameters). |
| • | Undrained condition: Select this option to estimate the bearing capacity in undrained conditions (total parameters). |
| • | Computation according to layers' weighted average: Select this option to calculate the foundation bearing capacity, based on the weighted average of the individual layer parameters. Not selecting this option causes only the parameters of the layer upon which the foundation is resting to be considered (Classic method). |
For each combination the user can reduce the characteristic parameters of the soil according to the imposed reduction coefficients and make the Seismic corrections in accordance with the selected design approaches.
For the calculation of seismic effects on the bearing capacity are proposed the maximum seismic ground accelerations that can be entered by the user.
LoadCap automatically identifies the worst computation combination and marks it with the symbol *.

Ks Computation
The computation of this constant is performed using the method suggested by Bowles.
