The Concrete Design add-on for RFEM allows you to perform the fire design of reinforced concrete walls and slabs according to the simplified table method (EN 1992‑1‑2, Section 5.4.2 and Table 5.8 and 5.9).
In the Concrete Design add-on, you have the option to define an existing vertically oriented punching shear reinforcement. This is then taken into account in the punching shear design.
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
Building stone on stone has a long tradition in construction. The Masonry Design add-on for RFEM allows you to design masonry using the finite element method. It was developed as part of the research project DDMaS - Digitizing the Design of Masonry Structures. Here, the material model represents the nonlinear behavior of the brick-mortar combination in the form of macro-modeling. Do you want to find out more?
For each load case, the deformations can be displayed at the end time.
These results are also documented for you in the printout report of RFEM and RSTAB. You can select the report contents and extent specifically for the individual design checks.
For a response spectrum analysis of building models, you can display the sensitivity coefficients for the horizontal directions by story.
These key figures allow you to interpret the sensitivity to stability effects.
The Timber Design add-on for RFEM 6 / RSTAB 9 is multi-purpose and combines a large number of additional elements. [*S16332764*] Timber Design Add-on for RFEM 6
You find the serviceability limit state design fully integrated in the result tables of the Timber Design add-on. If yuo want to check the design results, you can open the program and display the results with all the details at each location of the designed members. Furthermore, graphics are available for you with the result diagrams of the design ratios.
A special thing is that All result tables and graphics can be integrated into the global printout report of RFEM/RSTAB as a part of the timber design results. You can also display and document the deformations of the entire structure as a part of the RFEM/RSTAB functionality. This function is independent of the add-on.
Are you still looking for the design? The design checks are available in tabular form in the Timber Design add-on. Moreover, the program can also show you the distribution of the design ratios graphically. Extensive filter options are available for you in the table as well as in the graphical output, and you can use them to display the desired design checks by limit state or design type.

Your RFEM/RSTAB program is responsible for generating and calculating the load and result combinations required for the serviceability limit state. Select the design situations for the deflection analysis in the Timber Design add-on. The calculated deformation values are then determined at each location of a member, depending on the specified precamber and the reference system, and then compared to the limit values.
You can specify the deformation limit value individually for each structural component in Serviceability Configuration. In this case, the maximum deformation should not exceed the permissible limit value, depending on the reference length. When defining design supports, you can segment the components. This allows you to determine the corresponding reference length automatically for each design direction.
Based on the position of the assigned design supports, the program automatically determines the difference between beams and cantilevers. Thus, you can be sure that the limit value is determined accordingly.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.
- A wide range of cross-sections, such as rectangular sections, square sections, T‑sections, circular sections, built-up cross-sections, irregular parametric cross-sections, and many others (suitability for design depends on the selected standard)
- Design of cross-laminated timber (CLT)
- Design of timber-based materials and laminated veneer lumber according to EC 5
- Design of tapered and curved members (design method according to the standard)
- Adjustment of the essential design factors and standard parameters is possible
- Flexibility due to detailed setting options for basis and extent of calculations
- Fast and clear results output for an immediate overview of the result distribution after the design
- Detailed output of the design results and essential formulas (comprehensible and verifiable result path)
- Numerical results clearly arranged in tables and graphical display of the results in the model
- Integration of the output into the RFEM/RSTAB printout report
Do you have great respect for the ravages of time? After all, it eventually gnaws at your construction projects. Use the Time-Dependent Analysis (TDA) add-on to consider the time-dependent material behavior of members. Long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure. Prepare for this optimally with this add-on.
You can enter the structural system and calculate the internal forces in the programs RFEM and RSTAB. You have full access to the extensive material and cross-section libraries.
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.
The Dlubal structural analysis software does a lot of work for you. The input parameters, which are relevant for the selected standards, are suggested by the program in accordance with the rules. Furthermore, you can enter response spectra manually.
Load cases of the type Response Spectrum Analysis define the direction in which response spectra act and which eigenvalues of the structure are relevant for the analysis. In the spectral analysis settings, you can define details for the combination rules, damping (if applicable), and zero-period acceleration (ZPA).
Have you activated the Time-Dependent Analysis (TDA) add-on? Very well, now you can add time data to load cases. After you have defined the start and end of the load, the influence of creep at the end of the load is taken into account. The program allows you to model creep effects for frame and truss structures made of reinforced concrete.
In this case, the calculation is performed nonlinearly according to the rheological model (Kelvin and Maxwell model).
Was the calculation successful? You can now display the determined internal forces in tables and graphics, and consider them in the design.

Did you know? You can individually define the reference lengths to be considered in the calculation of the deflection limit value and the segments to be checked, depending on the direction. For this, define design supports at the intermediate nodes of a member and assign them to the respective direction for the deformation analysis. In the resulting segments, you can also define a precamber for each direction and segment.
