Design of Timber Members and Sets of Members

RF-/TIMBER Pro designs timber members and sets of members on the basis of the design procedures according to:

EN 1995‑1‑1 (including National Annexes; see below)
SIA 265:2012 + SIA 265‑C1:2012
DIN 1052:2008‑12

In addition to stress designs, RF‑/TIMBER Pro performs the stability analysis of members according to the equivalent member method or second‑order analysis as well as designs of the serviceability limit state and fire resistance. Furthermore, the module provides the option of automatic cross‑section optimization.

Input

After opening the module, it is necessary to select members or sets of members, load cases, load or result combinations for the ultimate and serviceability limit state designs and for fire resistance design. The materials from RFEM/RSTAB are preset and can be adjusted in RF-/TIMBER Pro. Material properties listed in the respective standard are included in the material library.

After the cross-section check, the module assigns the load duration classes (LDC) and the service classes (SECL) to the selected load cases and members.

Combined cross-sections may consist of various materials. The RF-/TIMBER Pro add-on module performs designs considering the shifted neutral axis (in the case of semi-rigid cross-sections). The deformation analysis requires the reference lengths of the relevant members and sets of members. Furthermore, you can define a specific direction of deflection, precamber, and beam type.
Design

The cross-section resistance design analyzes tension and compression along the grain, bending, bending and tension/compression as well as the strength in shear due to shear force with and without torsion. Designs proceed at the level of design stress values.

The design of structural components at risk of buckling or lateral buckling is performed according to the Equivalent Member Method and considers the systematic axial compression, bending with and without compressive force as well as bending and tension. Deflection of inner spans and cantilevers is determined in characteristic and quasi-permanent design situations.

Separate design cases allow for a flexible and stability analysis of members, sets of members, and loads. In the case of tapered members, the cut-to-grain angle is considered in the bending tension and bending compression area. If there is a ridge defined, the module performs the ridge design additionally.
Results

After the calculation, the module displays results in clearly arranged result tables. All intermediate values are included, providing a transparent design process. The results are listed by load case, cross-section, set of members, and members.

If the calculation fails, you can modify the relevant cross-sections in an optimization process. It is also possible to transfer the optimized cross-sections to RFEM/RSTAB to perform a new calculation.

Stress ratios are represented on the RFEM/RSTAB model by different colors in order to immediately recognize overdesigned or crucial areas of the model. Result diagrams of members and sets of members allow for targeted evaluation.

In addition to the input and result data in tables, you can add all graphics into the global printout report. In this way, a coherent and clearly arranged documentation is ensured.
