Design of Three-Hinged Frames with Finger Joint Connections

RX‑TIMBER Frame performs the ultimate and the serviceability limit state as well as fire resistance designs of three‑hinged frames according to EN 1995‑1‑1 (EC 5).

Optionally, it is possible to perform designs according to DIN 1052:2008‑12. In addition, fire resistance design according to EN 1995‑1‑2 or DIN 4102, Part 22, is possible as well.

  1. Features

    • Design of the following geometry types:
      • Symmetrical / asymmetrical
      • Half-frame
      • Column sloping inside / outside
      • Intermediate piece with / without
    • Direction of lamellas can be defined as parallel to inner or outer edge
    • In EC 5 (EN 1995), the following National Annexes are currently available:
      • United Kingdom BS EN 1995-1-1/NA:2009-10 (United Kingdom)
      •  ÖNORM B 1995-1-1:2015-06 (Austria)

      •  UNI EN 1995-1-1/NA:2010-09 (Italy)
      •  NEN EN 1995-1-1/NB:2007-11 (Netherlands)
      •  PN EN 1995-1-1/NA:2010-09 (Poland)
      •  STN EN 1995-1-1/NA:2008-12 (Slovakia)
      •  SIST EN 1995-1-1/A101:2006-03 (Slovenia)
      •  SS EN 1995-1-1 (Sweden)
    • Simple geometry input with illustrative graphics
    • Automatic generation of wind and snow loads
    • Automatic generation of required combinations for the ultimate and serviceability limit state as well as fire resistance design
    • Optional definition of load cases and load applications
    • Extensive material library for both standards
    • Optional extension of material library by further materials
    • Extensive library of permanent loads
    • Allocation of framework to service classes and specification of service class categories
    • Determination of design ratios, support forces, and deformations
    • Info icon indicating successful or failed design
    • Color reference scales in results tables
    • Direct data export to MS Excel
    • DXF interface for preparing production documents in CAD
    • Program languages: English, German, Czech, Italian, Spanish, French, Portuguese, Polish, and Russian
    • Verifiable printout report with all required designs availebe in many languages, for example English, German, French, Italian, Spanish, Russian, Czech, Polish, Portuguese, Dutch
  2. Geometrical data


    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.

    You can select the relevant timber grade of the material 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 and thus extend the library. Permanent loads (for example roof structure) can also be entered using the comprehensive and extendable material library.

    Generators integrated in RX-TIMBER Frame allow for comfortable 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, it is possible to enter load specifications manually. According to the generated loads, the program automatically creates combinations for the ultimate and serviceability limit state as well as for fire resistance design in the background. The generated combinations can be considered or adjusted by user-defined specifications.

  3. FE calculation


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

    • Designs to be performed:
      • Selecting the 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.

  4. .3 Design by Member


    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, transparency of all designs is ensured. Furthermore, it is possible to display the distribution of internal forces for each x-location of the beam in a separate graphical window where you can display the deformations and the individual internal forces.

    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.
