There are various options available for beam modeling. A roof type determines the exact purlin location for wind and snow generation.
Two beam types are available: continuous beam and purlin. If you select the continuous beam, it is possible to define several hinge conditions of the beam. If you select the purlin, it is not possible to modify hinge conditions. In this case, the calculation considers a double cross-section in the coupling zone. In addition, several coupling elements are available in the purlin settings:
- Nails (prebored/not prebored)
- Ring and plate connectors and bolts
- Screw connection with fastening system WT from SFS intec
- User-defined specification using characteristic strength
The relevant timber grade of the material can be selected from the material library. All material grades for glulam, hardwood and softwood timber specified in EC 5 are available. Furthermore, you have the option to generate a strength class with user-defined material properties and thus extend the library.A comprehensive and extensible material library can also be used for entering permanent loads (for example, roof structure).
Generators integrated in RX-TIMBER Purlin allow for convenient generation of various wind and snow load cases. By clicking the information buttons, the map of wind and snow zones for the relevant country is displayed. The corresponding zone can be selected with a double-click. Load cases can be checked graphically.
However, you can enter load specifications manually as well. According to the generated loads, the program automatically creates combinations for the ultimate and serviceability limit states as well as for fire resistance design in the background.
