Continuous tiedown systems are used to help resist overturning forces generated by lateral loads, and can be estimated in RISA-3D using the hold-down database and the strap forces.

When it comes to trusses in RISA-3D, boundary condition definitions (pin vs. roller) can make a huge difference. Let’s take an example of a typical roof truss.

When you have a plate model for a slab or wall in RISA-3D, the Internal Force Summation Tool (IFST) is a very useful analysis tool to get exactly the forces that you want to design for.

Aluminum has just been added to RISA-2D 10.0. This new Aluminum design allows you to design any shaped model using the Aluminum Design Manual 2005 specification.

Have you ever wanted to export your RISAFloor model to Revit? It’s easier than you’d think.
