| Pedestal Clear Cover
|
Type a concrete clear cover distance to be used for
the pedestal, if present, in the selected units.
|
|
Footing Clear Cover
|
Type a concrete clear cover distance to be used for the bottom-most layer of footing reinforcement, in the selected units. |
|
Unit Weight of Soil
|
Type a density to be used for the soil, in the
selected units.
|
|
Soil Bearing Capacity
|
Type the allowable bearing capacity of the soil, in
the selected units.
(US Codes only) If the
Use Variable Bearing Capacity option is
set in the
Global Settings dialog, then
select a bearing capacity table name from the drop-down list, instead.
|
|
Embedded Footing Depth
|
Type the depth from soil surface to the bottom of footing, in the selected units. |
|
Surcharge for Loading
|
Type a surcharge loading above the footing, in the
selected units.
For the stability check for calculating the factor of safety in sliding, surcharge is treated as a temporary load, meaning, it is treated as though there may be times when it is not present. Thus, its contribution to sliding resistance is not considered. That will reduce the total sliding resistance which will produce a more conservative result.
However, surcharge is considered when determining the soil bearing pressures under service loads since it leads to an increase in soil pressure.

|
Depth of Water Table
|
Type the depth from soil surface to the water table,
in the selected units.
If water table is not to be considered for this
footing, leave this value blank.

|
