RISA-3D will optimize your member size based on the analysis results. This means it will up or down-size your member to get closer to the unity/code check you’ve specified in your Design Rules.

This two-day comprehensive training course covers basic and advantages topics in a hands-on classroom environment. Learn to be a more efficient RISA-3D user by taking advantage of this course.

In RISAFloor on the roof level, you layout only the top chords of the truss and create your slope.

In RISAFloor, the beams are susceptible to two forms of buckling; Euler buckling and lateral-torsional buckling. The unbraced length is determined in RISAFloor using the deck properties and framing.

Using this method in RISAFloor, we are not actually designing the trusses, but just adding “dummy” bottom and top chords to correctly calculate the loading and help distribute the loads to the walls.
