Frame Distributed Load Definition

This tab is used to define linearly distributed loads that can be assigned to frames. The left pane displays a list of frame distributed loads available in the model, while the right pane shows the parameters of the selected load. The same area is also used to input parameters when creating a new frame distributed load.

1. Load case

Select the load case under which this load is defined.

2. + button

Opens the load case definition window so that you can add a new load case.

3. Load name

A unique name for the load. It can be left blank, in which case the program will generate one automatically.

4. Color

The color assigned to this load for visualization purposes.

5. Direction

Specifies the direction of the distributed load:

• FX: Force component in the global or local x-axis.
• FY: Force component in the global or local y-axis.
• FZ: Force component in the global or local z-axis.

6. Basis system

You can define the load in either the global coordinate system or the frame’s local coordinate system. The frame local coordinate system is illustrated below.

7. Position type

Specifies how the position of the load along the frame is defined. It can be given either in absolute terms or as a relative value between 0 and 1.

8. Intensity and position

Specifies the intensity of the distributed load along the frame. You must provide at least one intensity value. If only one value is provided, it is applied uniformly across the defined range.

Start and End define the start and end positions of the load along the frame. If not specified, the load is applied over the entire length of the frame. If defined as relative values, they must be between 0 and 1. If defined as absolute values, they must lie between 0 and the total length of the frame.

9. Delete button

Removes the selected load from the model.

10. Add button

Creates a new load using the specified parameters.

11. Modify button

Updates the parameters of the selected load.

12. Close button

Closes the window.
