How to Add a New Pattern to the Moving Load Database?

RISA-3D and RISA-2D come with a default list of existing moving load patterns.  These are listed in the Moving Loads Library which can be viewed by clicking on the Moving Load Patterns button Adding Moving Loads_1 or by selecting Modify – Moving Load Patterns Library.

The default options listed are common AASHTO loads, but you can also add a new pattern, edit a pattern, or delete a pattern.  Any changes you make will be saved to the database on your local computer and so the same library of moving loads will be available for use in other models.

You may combine lateral and vertical loads in the pattern, and you can define them in a number of ways.  The loading direction options are as follows:


To add a new pattern:

  • Click on the Add Pattern button to add a new moving load pattern.
  • Enter a Patten Label and your loading:

  • Click OK.

The Distance value denotes the distance between the previous load and the next load.  If you have two loads in different Directions but at the same location, you can enter a distance of 0, as is shown in the example above.  This example will result in loading like this:
