Answer:
The RX‑TIMBER Brace program is usually used to calculate the stiffening of duopitch roof beams with a variable cross-section height. They can be designed in the RX‑TIMBER Glued-Laminated Beam program.From the RX‑TIMBER Glued-Laminated Beam program, the user receives the equivalent loads per beam classified for each load case. The calculation is performed according to Section 9.2.5.3 of EC 5. This equivalent load must be transferred in the program RX‑TIMBER Brace for the identical load cases (Image 01).
Again, the axial forces calculated by the program RX‑TIMBER Brace must be defined as additional forces in the program RX‑TIMBER Glued-Laminated Beam. In this case, a distinction must be made between the compression force in the top flange of the brace and the tension force in the bottom flange of the brace. Both axial forces must always be applied separately. The tension forces of the bottom flange are used to derive a deflection force in the spatial system, which can be applied as an additional moment (Image 02).
