| Unit |
Select the unit of length (this page only).
|
| Foundation Type |
Select either Octagonal Foundationand Square foundation for the vertical vessel.
Tip: For vessels larger than 5 ft. in diameter, an octagonal foundation is typically more economical (this practice varies from user to user).
|
| Foundation Support Type |
Select whether the foundation is to be supported on a Soil Foundation or on a Pile Cap Foundation.

| Vessel Geometry group |
| Setting | Description |
|---|
| Effective Diameter (Dve) |
The effective diameter is the diameter that will be used to calculate the wind pressure on the vessel.
|
| Effective Height (Hve) |
The effective height is the effective height of the vessel that will be used to calculate the wind pressure and the seismic effect on the vessel.
|
|
| Pedestal Geometry group |
| Setting | Description |
|---|
| Diameter (Dp) |
Input pedestal diameter which will be used for shear check and pedestal design (as shown in the input page sketch).
|
| Thickness (Tp) |
Height of the pedestal from top of footing (as shown in the input page sketch)
|
| Bottom Of Footing Elevation (B.O.F) |
Bottom of footing elevation is used for detail drawing purpose. Based on this input elevation at top of concrete (T.O.C.), elevation at top of soil (T.O.S) and elevation at top of pedestal (T.O.P.) are displayed in detail drawing.
|
|
| Footing Geometry group |
| Setting | Description |
|---|
| Diameter (Df) Min / Max |
(Octagonal type) Specify the range of sizes used for checking in the design. The diameter is that of a circle on which the octagonal foundation is circumscribed in plan. The minimum diameter is first checked in the design process. If it is not adequate, then subsequent sizes are checked, up to the maximum diameter, until the design reaches the safety limit.
|
| Footing Dimension Increment |
This input is for increment interval for width/ length or diameter of the footing. |
| Length Min / Max |
(Square type) Specify the range of sizes used for checking in the design. The minimum length is first checked in the design process. If it is not adequate, then subsequent sizes are checked, up to the maximum length, until the design reaches the safety limit.
|
| Height (Tf) Min / Max |
Enter the minimum height which will be used in starting the design and will be checked up to the maximum value until the design reaches the safety limit.
|
|
| Overburden and Buoyancy group |
| Setting | Description |
|---|
| Depth of Water Table (Dw) |
Depth of the water tables measured from the ground level. This level is used to calculate buoyant force on the footing.
|
| Soil Depth (Ts) |
Depth of soil above the foundation measured from the top face of the footing base. Soil depth is used to calculate weight of soil over the footing
