RX-TIMBER Frame

RX-TIMBER Frame performs the ultimate limit state, the serviceability limit state, and the fire resistance design checks of three-hinged frames according to EN 1995‑1‑1 (EC 5).
You can optionally perform the design according to DIN 1052:2008‑12. Furthermore, it is possible to perform the fire resistance design according to EN 1995‑1‑2 or DIN 4102 Part 22.

RX-TIMBER Frame | Input

There are various options available for frame modeling. Graphical representations facilitate the geometry input. Modifications are updated automatically. Basic dimensions as well as geometrical data are entered in tables. During the input, the program checks the conditions required for the beam creation (for example, lamellas forming a curve) according to the defined standard. The most important geometry parameters are updated and displayed.

The relevant timber grade of the material can be selected from the material library. All material grades for glulam, hardwood, poplar and softwood timber specified in EN 1995-1-1 are available. Furthermore, it is possible to generate a strength class with user-defined material properties in order to extend the library. Permanent loads (for example, roof structure) can also be entered using the comprehensive and extensible material library.

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. The generated combinations can be considered or adjusted by user-defined specifications.

RX-TIMBER Frame | Design

In RX-TIMBER Frame, the following calculation settings are available:

Design of ULS, SLS, and/or fire resistance Selection of designs to be performed
Determination of displaying support forces and deformations
Adjusting the recommended limit values for the deformation analyses
Free definition of parameters for the fire resistance design performed 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 analyses. You can define the design type to be performed in the Control Parameters window.

RX-TIMBER Frame | Results

After the calculation, the results of performed designs, including all required intermediate values, are displayed in clearly arranged result tables sorted by various criteria. Since the program displays the intermediate values in detail, the transparency of all designs is ensured. It is possible to display the distribution of internal forces for each x-location of the beam in a separate graphical window. Here, both the deformations and the individual internal forces can be displayed.

Designs with design details and selected result diagrams can be added in the printout report, providing clearly arranged documentation. The printout report can include graphics, descriptions, drawings, and more. Moreover, it is possible to select which calculation data will be covered in the printout.
