How to Model X-Bracing in RISA-3D
There are several tips to modeling X-Bracing within RISA-3D that can help the model solve faster and give you better results.
Halloween isn’t just for candy and costumes—it’s the perfect time to test your spooky engineering skills! We’ve brewed up a Halloween-themed RISA Jeopardy game, packed with fun, easy questions about our software. Tip for readers: Try to answer before revealing the “treat” below each question! 💀 Can You Count? 100 – RISACalc: How many components are currently available in RISACalc? 10 (Beam, Column, Steel Joist, Composite Beam, Retaining Wall, Spread Footing, Wall Footing, Drilled Pier, Seismic Load, Wind Load) 200 – FD: How many Data Entry spreadsheets are available in RISAFoundation? 25 300 – RISA-3D: How many countries or regions have building codes supported in RISA-3D? 9 (US, Canada, Mexico, Europe, Great Britain, India, Australia, New Zealand, Saudi Arabia) 🎃 Adaptable 100 – ADAPT: Which of these is not an ADAPT product? ADAPT-Builder, ADAPT-Felt, ADAPT-Floor, ADAPT-ABI ADAPT-Floor 200 – ADAPT: Which mode of ADAPT-Builder is used to design slabs-on-grade on expansive soils using the PTI method? ADAPT-SOG 🕸️ The Whole Family 100 – Other: This steel detailing software and fellow Nemetschek brand has a built-in export option in RISA-3D. SDS2 200 – Other: Which design code is the most common in our software, found in 8 of our 10 programs?…

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. Note that a pin-pin boundary condition has been applied to the ends.
If you have ever tried to solve a two-dimensional model in RISA-3D, you have ultimately run into instabilities in your model because your model has no out of plane restraint.
Do you get an instabilities warning when you’re trying to do a simple 2D model in RISA-3D?
