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

How to Work Effectively with the Building Model Add-on in RFEM 6
Building Model is one of the special solution add-on modules in RFEM 6. It is an advantageous tool for modeling, with which building stories can be created and manipulated easily. Building Model can be activated at the beginning of the modelling process and afterwards.

Model Types in RFEM 6
Structures are three-dimensional in reality; however, they can be simplified and analyzed as 2D or 1D models. The model type has a crucial influence on how the structural components are stressed, and it should be defined prior to modeling and calculation. The model types available in RFEM 6 are shown in Image 1.

5 Main Differences Between RFEM 6 and RFEM 5
The new generation of the RFEM software is an intuitive, powerful, and easy-to-handle 3D FEA program that meets all up-to-date demands in modeling, calculation, and structural design. The modern design concept as well as the introduction of new features make the program even more innovative and user-friendly. The main differences between RFEM 6 and its previous version RFEM 5 are discussed in the following.

Using Load Transfer Surface in RFEM 6
This article explains the use of surfaces with the Load Transfer stiffness type in RFEM 6. A practical example is also provided to demonstrate the application of self-weight, snow load and wind load to a steel hall.

Failing Support Conditions for Contact Surfaces
In order to create a surface model with failing supports close to reality, an option called "Failure if contact perpendicular to surfaces failed" is available in RFEM 5 for contact solids under "Contact Parallel to Surfaces".

Simplified Blast Design According to AISC Steel Design Guide 26
Blast loads from high energy explosives, either accidental or intentional, are rare but may be a structural design requirement. These dynamic loads differ from standard static loads due to their large magnitude and very short duration. A blast scenario can be carried out directly in a FEA program as a time history analysis to minimize loss of life and evaluate varying levels of structural damage.

Parametrization of Rolled Cross-Sections
Rolled sections, the most common cross‑section type in RFEM and RSTAB, can also have user‑defined parameters. To do this, select the cross‑section to be modified in the cross‑section library and click the [Parametric Input...] button.

Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Columns
This article compares the design to the one in the referenced article: Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members. It is, therefore, about taking exactly the same theoretical application carried out in RF-CONCRETE Members and reproducing it in RF-CONCRETE Columns. Thus, the objective is to compare the different input parameters and the results obtained by the two add-on modules for the design of column-like concrete members.

Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members
This article deals with rectilinear elements of which the cross-section is subjected to axial compressive force. The purpose of this article is to show how very many parameters defined in the Eurocodes for concrete column calculation are considered in the RFEM structural analysis software.
