# Girder Load \[CBG]

## Girder Load

Girder loads can be defined based on the selected girder, construction stage, applied flange, and magnitudes in terms of forces and moments.

**Girder**: Select the girder to which the load will be applied.

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

**Applied Flange \[Top/Bottom]:** Specify the flange as either the top or bottom using this parameter.

**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.
