# Bottom of Column Forces \[TB]

To define the columns bottom node results for forces and moments in all directions to be shared, this object can be utilized. For this object to function properly, users must ensure that the FEA has been run for the model.

## General

**Column:** Specify the column.

**Extract From \[Result Case/ Load Combination Table]**: This parameter can be specified using the options provided: either Result Case or Load Combination Table. Further definitions can be made by the parameters Result Case or Load Combination Table.

**Result Case**: If the parameter *Extract From* is defined with the option *Result Case*, this parameter can be used to further define the specific case from which the specified bottom column node forces will be extracted for sharing. If *Extract From* is defined with the option *Load Combination Table*, this parameter will not be applicable (N/A).

**Load Combination Table**: If the parameter *Extract From* is defined with the option *Load Combination Table*, this parameter can be used to further define the Load Combination Table from which the specified bottom column node forces will be extracted for sharing. If *Extract From* is defined with the option *Result Case*, this parameter will not be applicable (N/A).

**Limit State**: Users can specify the limit state based on which the results will be extracted. This parameter can only be specified if the *Extract From* parameter is defined with the option *Load Combination Table*.

## Force Extraction Settings

**Maximize Force (Target Element Local)** : Users can choose to maximize results for all forces and moments (Fx, Fy, Fz, Mx, My, and Mz) or for a specific component individually. This parameter can be defined using the options visible in the pop-up window when the 'Select' option is chosen.

**Min/Max \[Abs. Max/Max/Min]**: *Maximum* represents positive values, *Minimum* represents negative values, and *Absolute Maximum* refers to the largest value by magnitude, whether positive or negative.

**Set Max Target \[Self/Target]**: The bottom column node results can be extracted by filtering to display either the maximum result of the node itself or the maximum result obtained for a specified target.

**Pile Layout**: If the *Max Target* parameter is set to *Target*, this parameter can be used to specify the related pile layout.

**Pile Layout Pile Index**: For the specified pile layout, this parameter can be used to define the specific index.

**Report Extracted Forces Coord. Sys.**:

## Extracted Forces

This tab displays the specified results along with details of the cases/load combination tables, force settings, and the date and time of the result extraction.

**Extracted From**: The specified result case or load combination table is displayed in this column.

**Force Settings**: Details of the extracted forces are displayed in this column.

**Last Result Extraction**: The date and time of the last result extraction are displayed in this column.

**Fx**: Read-only value representing the reaction force at the bottom of the column along the X-axis.

**Fy**: Read-only value representing the reaction force at the bottom of the column along the Y-axis.

**Fz**: Read-only value representing the reaction force at the bottom of the column along the Z-axis.

**Mx**: Read-only value representing the moment at the bottom of the column along the X-axis.

**My**: Read-only value representing the moment at the bottom of the column along the Y-axis.

**Mz**: Read-only value representing the moment at the bottom of the column along the Z-axis.

**Coordinate System**: The coordinate system for which the results are displayed is shown in this column.
