Beaver is a tool that allows timber engineering procedures to be executed in computational design workflows. The tool was developed following the “Eurocode5 - Design of Timber Structures” for verifying frame cross-sections, deformations and design of fastener-type timber connections. Also, Beaver is now fully integrated to Karamba3D.

Beaver was conceived at the Polytechnic School of the University of São Paulo - Brazil, and currently developed by engineers João Pini, Márcio Sartorelli and Renan Prandini. If you detect any bugs or inaccuracies please let us know.

We have recently published a scientific article in the World Conference of Timber Engineering (WCTE) 2023 showcasing the capabilities of Beaver, make sure to quote us on your research and projects.
