Aluminum has just been added to RISA-3D 9.0. This new Aluminum design allows you to design any shaped model using the Aluminum Design Manual 2005 specification.

The typical application of lateral loads on Rigid diaphragms occurs at the center of mass for that diaphragm. This requires that joints are created at this location and lateral loads are applied at these joints.

RISAFoundation now has the ability to automatically generate a circular slab with just a few easy clicks. Using the generator the program will create the mat slab and tank loading all in one easy step.

In order to understand the interaction between plates and members it is important that you know the basics of Physical Members and Plate Connectivity.

In RISA-3D and RISA-2D, it’s easy to draw web members for trusses with equal web spacing along the chord length. You can simply “split” the chord into equal segments.
