The Dlubal development team is pleased to announce the availability of COMPOSITE-BEAM 8.25.01, a useful construction program for structural analysis and design of composite beams according to: ENV 1994-1‑1:1992‑10.
Update Report No. 03237 COMPOSITE-BEAM 8-25-01 | 02/18/2021
- Adaptions concerning the design of the plastic resistance moment for partial shear connections.


COMPOSITE-BEAM automatically analyzes the resulting internal forces and carries out all relevant verification according to following the standards. The results are displayed in the spreadsheet masks. They are sorted by the required analysis standards and thus enable an easy orientation. The user`s control over the input as well as the interpretation of the results is facilitated through 3D visualization. All graphics can be edited and transferred to the Printout Report.
An example in civil structures is the steel-concrete composite beam in which a steel wide-flange shape (I or W shape) is attached to a concrete floor slab. The many other kinds of composite beam include steel-wood, wood-concrete, and plastic-concrete or advanced composite materials-concrete.Composite beams as defined here are different from beams made from fiber-reinforced polymeric materials.
The Dlubal COMPOSITE-BEAM program performs design of composite beams according to: ENV 1994‑1‑1:1992‑10
The program is based on bidirectional communication between RSTAB and the add‑on modules. However, an RSTAB license is not required for using COMPOSITE‑BEAM (stand‑alone operation is possible).
How can I create a printout report for COMPOSITE‑BEAM?

System Requirements.
In order to use Composite Beam without any difficulties, the following system requirements are recom-mended:
- Operating system Windows XP/Vista/7/8
- x86 CPU with 2 GHz
- 2 GB RAM
- 10 GB hard disk capacity, including approximately 4 GB required for the installation
- Graphics card with OpenGL acceleration and resolution of 1024 x 768 pixels. Onboard solutions and shared-memory technologies are not recommended
RSTAB is not supported by Windows 95/98/Me/NT/2000, Linux, Mac OS or server operating systems.
No product recommendations are made, with the exception of the operating system, as RSTAB basically runs on all systems that fulfill the system requirements mentioned above. If RSTAB is used for intensive calculations, the guiding principle 'more is better' applies.
When complex structural systems are calculated, huge amounts of data are produced. As soon as the main memory is not sufficient for taking the data, the hard drive will take over, which can slow down the computer significantly. Therefore, upgrading the main memory will usually speed up the calculation more than a faster processor.
As the RSTAB analysis core supports several processor kernels, you can completely exploit the potential of 64-bit operating systems. For 32-bit systems the memory size used by the proces-sor is limited to 2 gigabytes. Therefore, more memory can be used with the 64-bit technology. If you work with a computer having sufficient RAM memory using a 64-bit operating system, it is possible to calculate also big models.
To calculate complex structural systems, we recommend to use the following configuration:
- Quad-core processor
- Windows 7 64-bit
- 8 GB RAM
