Bonanza 2500

Bonanza 2500 draws the line of thrust through a dry-stone wall while you build 🔨 it, and tells you the moment the stack stops standing up. Dry-stone and corbelled masonry holds together by weight and friction alone, with no mortar anywhere. Whether it stands depends on where the load line runs inside the stones. Stack courses in section, shift them, overhang them, and watch 👀 that line move. What the bench computes, live: - The thrust line through every bed joint in the stack - The governing joint, named and highlighted - The failure mode: stable, joint opening, crushing, sliding or overturning - The middle-third rule, drawn rather than described - Coulomb sliding checks at each course - Peak bearing stress at the compressed edge - A geometric safety factor for the whole wall - A pseudo-static seismic coefficient you can raise until it fails Corbelling is where it gets interesting. Push a course out past the one below and Bonanza 2500 bears only on the true overlap, which is exactly what makes a corbelled arch possible and exactly what limits how far it can reach. Build 🔨 your own sections in the editor, browse a gallery 🖼️ of classic profiles to start 🚀 from, save 💾 any wall as an image, and keep a history of what you have tested. Every method the engine uses is written out in plain language, with a glossary for the terms. A learning and exploration tool 🛠️ for anyone curious about how old walls stay up: students, builders, conservation volunteers and the plain curious. It is not a certified design instrument, and the app 📱 says so where it matters. No account, no internet, no adverts. Open Bonanza 2500 and see 👀 how far you can corbel before it falls.
