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.
