Structural system
  • Cross-section
  • Multi-part cross-sections are possible
  • Weakening of the cross-section is possible
  • Design with characteristic loads
  • Additional load cases can be defined
  • Hot design is possible

For the verifications in accordance with EN 1995, the user can optionally determine the design internal forces from the combinations for the ultimate limit state design as per EN 1990.

The verifications are performed for solid timber. The fire-safety verifications are based on EN 1995-1-2.

The coordinates of the local members and cross-sections comply with the specifications of DIN 1080. The x-axis runs in direction of the positive member axis. The y- and z-axes lie inside the cross-section and the positive z-axis points downwards. The x-y-z system consists of three orthogonal legs.


Internal forces and geometric vectors are positive if they are oriented in the direction of the positive axes. The moments My and Mt are positive if they describe a right-hand helix about the y- and x-axes. Whereas the bending moment Mz is positive, according to structural conventions, when it describes a right-hand helix in direction of the negative z-axis in such a way that tension is produced on the positive cross-section sides (dashed lines) when a positive moment load applies.
