Timber Design for RFEM 6

The Timber Design add-on is ideal for design of timber structures! It allows you to perform the resistance design and stability analysis of beam and plate structures (RFEM) in the ultimate limit state. It provides a wide range of cross-sections, including rectangular sections, square sections, T‑sections, and irregular parametric sections.

It supports the design of cross-laminated timber (CLT), as well as wood-based materials and laminated veneer lumber according to EC 5. Users can adjust important parameters and design values. The quick and clear result output contains detailed information about the essential formulas, which are easy to understand.

Cross-Section Resistance Features

The program performs the calculations of tension, compression, bending, shear, torsion, and combined internal forces. There is and option to design the compression perpendicular to the grain on the end and intermediate supports with (according to EC 5) and without reinforcement elements (fully threaded screws).

The system considers higher strength for similar components that are close to each other by using the k_sys factor according to EN 1995‑1‑1, 6.6(1)‑(3).

Stability Design

The program provides various powerful features, such as the calculation of internal forces, compression design, identification of the stronger side, reduction of shear forces, design of curved elements, increase of shear strength, standard-dependent selection options, as well as clear results with a detailed cost overview.

The structural system allows for the alternative consideration of all effects for stability analyses (second-order analysis, imperfections, and stiffness reduction) already during the determination of the internal forces in RFEM/RSTAB, optionally in combination with the Torsional Warping (7 DOF) add-on.

Results

If your design is successful, the relaxed part of your work follows. Because the program does many processes for you. For example, the performed design checks are displayed in a table. It shows you all the result details. Due to the clearly presented design formulas, you will be able to understand the results without any problems. There is no "black box" effect here.

Input

Timber Design is completely integrated into the main programs. At the same time, it automatically takes into account the structure and the available calculation results. You can assign further entries for the timber design, such as effective lengths, cross-section reductions, or design parameters, to the objects to be designed. You can easily select the elements graphically using the [Select] function at many places of the program.

Fantastic and Professional Support

I would just like to send a quick note to wish everyone at Dlubal well, in particular I would like to say thank you for the fantastic, thorough and professional support you provide.

Powerful, Easy to Use, Easy to Learn…

We adopted Dlubal in our work and haven't looked back. Powerful, easy to use, easy to learn, with mercifully simple output (once set up).
