Eurocodes (EC)

Structural Design with RFEM and RSTAB According to European Technical Standards (EC)

Eurocodes

The Eurocodes (EC for short) are standardized rules for designing in civil engineering throughout Europe.

There are currently 10 Eurocodes (EC 0 to EC 9 in the standards EN 1990 to EN 1999). These are further subdivided. The Eurocode consists of 58 partial standards.

In addition, the standards committees of the member states create a National Annex for each Eurocode, in which the parameters to be defined nationally, such as partial safety factors, are defined.

Structure of the Eurocode:

Eurocode 0: Basics
Eurocode 1: Actions
Eurocode 2: Concrete structure
Eurocode 3: Steel structure
Eurocode 4: Composite construction
Eurocode 5: Timber structure
Eurocode 6: Masonry construction
Eurocode 7: Foundation
Eurocode 8: Earthquake
Eurocode 9: Aluminum structures

Most Suitable Software for Structural Analyses According to Eurocodes

“We decided to work with RFEM by Dlubal Software for the calculation of our three-dimensional steel structures after the analysis of different offers on the market. It is the software which seems to be the most suitable for analyses according to Eurocode standards. With its clear and intuitive interface, the data and the results can be entered visibly and editably in a smooth and efficient way which minimizes the effect of a "black box".

The technical support is remarkably patient, competent and responds quickly which confirmed our decision in favor of RFEM. The tutorials, the blog and the detailed user manuals allow a self-study and a comprehensive initial training and then a continuous learning of new functions. A further positive aspect is the modular structure which makes it possible to enlarge the offer based on the same main program without important learning phase. Even if we decide tomorrow to focus more in timber, aluminum or glass structures, the calculation will not be a blocking element for us.”

Eurocodes in Practice

Options for Splitting Surfaces

If you want to split a surface limited by four sides into several surfaces, the easiest way to do this is to use the "Split Surface" function.

Implemented Eurocodes

Combinations according to Eurocode 0 (EC 0)

In both main programs RFEM and RSTAB, load and result combinations are generated according to Eurocode 0 (EN 1990). In addition, it is possible to determine imperfections in compliance with Eurocode. The actions are assigned to the action types described in the standard. According to the selected design situation, RFEM and RSTAB subsequently combine the load cases.

Actions according to Eurocode 1 (EC 1)

RFEM and RSTAB provide the option to generate wind and snow loads. No additional module is needed for the generation. When the required parameters like wind and snow load zone, terrain category, topography type or roof geometry are entered, the program creates the respective loading automatically.

Reinforced and prestressed concrete structures according to Eurocode 2 (EC 2)

The extension EC2 for RFEM/RSTAB of the add-on modules RF-/CONCRETE and RF-/CONCRETE Columns as well as RF‑PUNCH Pro allows you to perform the reinforced concrete design of beams, columns, and surfaces according to Eurocode. In addition to the general ultimate and serviceability limit state design, it is possible to perform stability analyses for columns according to EC 2. For columns and members, you can also carry out fire resistance designs according to Eurocode.
