Structural Frame Analysis Program RSTAB

Structural Engineering Analysis & Design Software

The 3D structural frame analysis program RSTAB is the ideal tool for the design of beam, frame, or truss structures consisting of steel, reinforced concrete, timber, aluminum, or other materials.

With RSTAB you can easily and quickly define a structural model and then calculate the internal forces, deformations, and support reactions. For further design, there are various add‑on modules available, considering structural data of specific materials and standards.

The Best Structural Modeling Program

"“We are dealing with Structural and Seismic Engineering since 1998. According to our experience, Dlubal Software is absolutely the best structural modeling program. We recommend it to all those who need to face particular cases and daily cases ''.

As a standard feature, RSTAB includes helpful tools for generating wind, snow, and ice loads, etc., as well as for converting surface loads into member loads.

Snow Load Generator
Snow loads can be generated as member loads on flat/monopitch roofs and duopitch roofs.
Additional snow loads such as drifted snow loads, snow overhangs, and snow guards can be taken into account as well.
The following standards are available:
- 1991-1-3 (including National Annexes)
- DIN 1055-5
- CTE DB-SE-AE
- ASCE/SEI 7-16
- More Information
Wind Load Generator
Wind loads can be automatically generated as member loads on the following structural components (optional with internal pressure für open buildings):
- Vertical walls
- Flat roofs
- Monopitch roofs
- Duopitch/Troughed roofs
- Vertical walls with roof
The following standards are available:
- 1991-1-4 (including National Annexes)
- DIN 1055-4
- CTE DB-SE-AE
- ASCE/SEI 7-16
- More Information
Generating Member Loads from Area Loads
Area loads can be automatically converted into member loads. There are 2 options available for this:
- Member loads from area loads via plane
- Member loads from area loads via cells
Depending on the selected option, you either have to define a plane via corner nodes or select cells in the graphic. The area load can either be applied to the entire surface or only the effective or projected surface of the members.
- More Information
Generating Member Loads from Free Line Loads
With this generator, you can define free line loads e.g. for girder grillages (from conveyor belts, for example) and proportionally allocate them to members.
- More Information
Generating Member Loads from Coating
Coating loads can be generated as member loads from ice loads, claddings, etc.
For that, you only have to specify the thickness and specific weight of the coating.
- More Information
Generating Loads from Accelerated Motion
This generator creates loads as a result of an acceleration or rotation (from tower cranes, for example), which acts on specific objects of the model.
The mass is determined from the self-weight.
