RX-TIMBER Brace | Input
The geometry is entered by means of templates as 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. 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.
Since the stiffening bracing includes also the steel cross-sections, current steel grades are integrated in the library as well. Therefore, there are also the rolled and welded cross-sections available. Stiffening 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 divided by the partial safety factor for the design of the bearing capacity and with the mean values of the stiffness for the serviceability limit state design. The loading can be entered directly as a lateral load (equivalent lateral load) resulting from a truss girder design.
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, the program automatically creates combinations for the ultimate and serviceability limit state as well as for the fire resistance in the background. The generated combinations can be considered or adjusted by user-defined specifications.
