Various options are available to model the frame. To facilitate the geometry input, graphical representations are displayed. Modifications are updated automatically. Basic dimensions as well as geometrical data are entered in tables. During the input, RX-TIMBER Frame already checks the conditions required for the creation of the beam (for example lamellas forming a curve) according to the defined standard, and the most important geometry parameters are updated and displayed.

Concerning material settings, it is possible to select the relevant timber grade from the material library. All material grades specified in EN 1995-1-1:2004 (EC5) or DIN 1052:2008-12 and the selected National Annex are available for gluelam, leafy and coniferous timber. Furthermore, it is possible to generate a strength class with user-defined material properties in order to extend the library.

For the input of permanent loads (for example roof structure) you can use as well a comprehensive material library that can be extended. The generators integrated in RF-TIMBER Frame allow for a comfortable creation of various wind and snow load cases. The map showing wind and snow zones of the relevant country can be displayed by clicking the information buttons. The corresponding zone can then be set by double click. The load cases are represented graphically so that you can check the loads. Manual load specifications are possible as well.

According to the generated loads, RF-TIMBER Frame creates combinations for the ultimate limit state, the serviceability limit state and for fire protection automatically in the background. By means of the add-on module RF-COMBI, you can analyze the generated combinations and, if necessary, adjust them by user-defined settings.

The following calculation settings can be defined:

• Designs to be performed:
• Selecting the designs that you want to perform
• Determining whether support forces and deformations are displayed or not
• Adjusting the recommended limit values for the deformation analyses
• Free definition of parameters for the fire protection design carried out according to the simplified method
• Increasing bending stiffnesses for flat-ended bending strains

Separate design cases allow for a flexible analysis of specific actions as well as for individual stability checks. The type of design that you want to perform can be defined by control parameters.

Furthermore, it is possible to display the distribution of internal forces for each x-location of the beam in a separate graphic window. RF-TIMBER Frame can represent the deformations as well as the individual internal forces.

The designs including design details and selected result diagrams can be integrated in the printout report, which ensures a clearly-structured documentation. The printout report can be completed by graphics, descriptions, drawings etc. Moreover, it is possible to define individually which calculation data will appear in the printout.
