Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Stability analysis of a purlin with I-section without fork support
This technical article deals with the stability analysis of a roof purlin, which is connected without stiffening by means of a screw connection on the lower flange in the sense of a minimum manufacturing effort.

Lateral-Torsional Buckling in Timber Construction | Examples 1
The article Lateral-Torsional Buckling in Timber Construction | Theory explains the theoretical background for the analytical determination of the critical bending moment Mcrit or the critical bending stress σcrit for the lateral buckling of a bending beam. The following article uses examples to verify the analytical solution with the result from the eigenvalue analysis.

Fire Resistance Design of a Column Under Axial Force
In this technical article, a hinged column with a centrally acting axial force will be designed by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-2. We will use the National Annex of Germany here.

Timber Column Design per the 2018 NDS Standard
Using the RF-TIMBER AWC module, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling in RF-TIMBER AWC using step-by-step analytical equations per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.

Calculating Effective Lengths on the Example of a Double-Story Frame
With the RF-STABILITY or RSBUCK add-on modules for RFEM and RSTAB, it is possible to perform eigenvalue analyzes for member structures in order to determine the effective length factors. The effective length coefficients can then be used for the stability design.

Considering Tension Members in Dynamic Analysis
Both the determination of natural vibrations and the response spectrum analysis are always performed on a linear system. If nonlinearities exist in the system, they are linearized and thus not taken into account. Straight tension members are very often used in practice. This article will show how you can display them approximately correctly in a dynamic analysis.

Effect of Member Eccentricities When Calculating Internal Forces
The beam is resting on the column and the beam ends at the outer edge of the column. These requirements can be easily fulfilled in an architectural model with solids. In member analysis, simplified line models are used in which center lines meet in a common node. In this article, the influence of member eccentricities on the determination of internal forces is shown on three simple models.

Snow Load on Elevated Solar Thermal and Photovoltaic Systems on Roofs up to 10 ° Inclination
In the existing standard, there were no regulations for the distribution of snow loads for elevated solar thermal and photovoltaic systems on roofs. It was only advised to distribute the loads. Only with the National Annex DIN EN 1991-1-3/NA: 2019-04, concrete rules have been taken for this.
