RX-TIMBER Brace 2.xx

The geometry is entered by means of templates like it is done in all other programs of the RX-TIMBER family. By selecting the roof structure you define the base geometry which can be adjusted by user-defined settings.

Furthermore, it is possible to import the geometry directly from a structure created in RX-TIMBER Glued-laminated Beam.

The relevant timber grade can be selected from the material library. All material grades specified in DIN 1052:2008-12 or EN 1995-1-1:2004 (EC5) and the selected national annex are available for gluelam, leafy and coniferous timber. In addition it is possible to generate a strength class with user-defined material properties in order to extend the library. As steel cross-sections are also used in stiffening bracings, current steel grades are integrated in the database, too.

Therefore, the program also offers rolled and welded sections for the cross-section input.

Stiffenings of coupling elements can be considered in table 1.5 Connections as translational and rotational spring stiffnesses. The program handles these stiffnesses with a stiffness that is divided by the partial safety factor for the design of the bearing capacity and with the mean values of the stiffness for the design of the serviceability.

The loading can be entered directly as a lateral load (equivalent lateral load) resulting from a truss girder design. The wind load is applied automatically to all four sides of the structure. Additionally, you can specify user-defined loads, for example concentrated loads from columns (buckling load).

According to the generated loads RX-TIMBER Brace 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 in RX-TIMBER Brace:

• Selection of designs that you want to perform
• Optional output of support forces and deformations
• Adjustment of recommended limit values for deformation analyses in the ultimate and the serviceability limit state design
• Free definition of parameters for the fire protection design carried out according to the simplified method
• Consideration of material non-linearities (failing members)

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

Subsequent to the design, RX-TIMBER Brace shows all performed designs including all required intermediate values in clearly arranged tables, sorted by different criteria. As the program displays even the intermediate values in detail, transparency for all designs is guaranteed.

Furthermore, it is possible to display the result diagram for each location x on the beam in a separate graphic window. RF-TIMBER Brace can represent deformations as well as 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 specify the calculation data which you want to appear in the printout.
