RX-TIMBER Roof | Input

There are various options available for modeling a roof. Graphical representations facilitate the geometry input. Modifications are updated automatically.

In addition, it is possible to consider cross‑section weakening on supports. Optionally, you can define if the design of support pressure on the rafter side should be performed.

Permanent loads (for example, roof structure) can be entered using the comprehensive and extensible material library. Loads due to cantilevers and collars/ties can be entered separately. Generators integrated in RX-TIMBER Purlin allow for convenient generation of various wind and snow load cases. You can manually add any concentrated and distributed loads.

Load cases are displayed graphically and superimposed in automatically generated load combinations according to EC 5. For stability and serviceability limit state designs, you can change the data manually, for example, for example, for cantilevers (roof overhang), it is necessary to ignore the SLS.

• Design of the following roof types:
  • Flat Roof
  • Monopitch roof
  • Duopitch roof (symmetrical/asymmetrical)
