🎃 Trick or Treat… It’s RISA-Jeopardy! 👻

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?…
