# Footing Point Load \[TB]

Point loads on footings can be applied based on the specifications defined using the parameters below.

## Footing Point Load

**Footing:** Specify the footing to which the load will be applied.

**Stage:** Choose the stage at which to apply the load.

**Specify Position As \[Point/Column Center]:** If the **Point** input method is selected, the engineer must specify a position relative to the footing center. If **Column Center** is selected, the engineer must specify a column. The load will then be positioned at the center of the specified column.

**X Position (Center is (0,0)):** For point loads with the "Specify Position" parameter set to the option **Point**, the X coordinate (always along the longitudinal direction, regardless of the footing's rotation) can be specified using this parameter.

**Y Position (Center is (0,0)):** For point loads with the "Specify Position" parameter set to the option **Point**, the Y coordinate (always positive to the right when looking upstation along the PGL direction, regardless of the footing's rotation) can be specified using this parameter.

**Column:** This input is enabled if **Specify Position As** is set to **Column Center**. Specify the column. The load will be positioned at the column's center, where it connects to the footing.

**Fx:** Force in the longitudinal direction along the PGL.

**Fy:** Force in the direction perpendicular to the PGL.

**Fz (Gravity):** Force in the vertical direction. A positive value indicates a load in the global -Z or gravity direction. For usual loads (wearing surface loads - stay-in-place formwork loads), the user should input positive values.

**Mx:** Moment in the longitudinal direction along the PGL.

**My:** Moment in the direction perpendicular to the PGL.

**Mz:** Moment in the vertical direction.

{% hint style="info" %}
Although **Fz** is applied in the direction of gravity (positive values for **Fz** will correspond to the downward direction, as with gravity), **Mz** will have a positive direction relative to the **+Z** axis or, in other words, in the upward direction.

**The Directions of Forces** For footings with a rotation parameter defined as a value other than zero, the directions of the applied loads are adjusted accordingly. Refer to the figures provided below for further clarification on the directions of positive forces and moments. ![image-20250122-154742.png](https://openbrim.atlassian.net/wiki/download/attachments/2826698753/image-20250122-154742.png?api=v2) ![image-20250122-154636.png](https://openbrim.atlassian.net/wiki/download/attachments/2826698753/image-20250122-154636.png?api=v2) ![image-20241214-114956.png](https://openbrim.atlassian.net/wiki/download/attachments/2826698753/image-20241214-114956.png?api=v2) ![image-20241214-114849.png](https://openbrim.atlassian.net/wiki/download/attachments/2826698753/image-20241214-114849.png?api=v2)
