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 subdivided further. The Eurocode consists of 58 partial standards. Furthermore, the standards committees of the member states create a National Annex for each Eurocode, which contains the national definition of the parameters, such as partial safety factors.
Structural Analysis and Design Software for Eurocodes (EC)
Standards and codes are important. Where do you plan your project and what do you have to pay attention to? When it comes to international standards, the Dlubal programs are reliable companions for customers from all over the world. You will find numerous standards integrated in RFEM and RSTAB, whereby the corresponding add-ons allow you to design steel, reinforced concrete, and timber structures. Here you will find an overview of the standards available in the programs for the respective countries.

Combinations According to Eurocode 0 (EC 0)
Plan your buildings safely and according to the European standards. In both main programs RFEM 6 and RSTAB 9, you can easily and efficiently generate load and result combinations according to Eurocode 0 (EN 1990). Furthermore, it is also possible to determine imperfections according to Eurocode in both programs. The actions are assigned to the action types of the standard. RFEM and RSTAB then combine the load cases according to the selected design situations.

Actions According to Eurocode 1 (EC 1)
Do you want to make sure that your structure can withstand any weather? Then you only need the main programs RFEM 6 or RSTAB 9. Both programs provide you with the option of generating wind and snow loads without any additional add-ons. After entering the required parameters, such as wind and snow load zone, roof geometry, and so on, the program automatically generates the respective loading.

The coefficient θ is calculated as follows:$$\mathrm\theta\;=\;\frac{\displaystyle{\mathrm P}_\mathrm{tot}\;\cdot\;{\mathrm d}_\mathrm r}{{\mathrm V}_\mathrm{tot}\;\cdot\;\mathrm h}\;$$
Do you have individual column sections and angled wall geometries, and need punching shear design for them?
No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.
The building model is calculated in two phases:
- Global 3D calculation of the global model, where the slabs are modeled as a rigid plane (diaphragm) or as a bending plate
- Local 2D calculation of the individual floors
After the calculation, the results of the columns and walls from the 3D calculation and the results of the slabs from the 2D calculation are combined in a single model. This means that there is no need to switch between the 3D model and the individual 2D models of the slabs. The user only works with one model, saves valuable time, and avoids possible errors in the manual data exchange between the 3D model and the individual 2D ceiling models.
The vertical surfaces in the model can be divided into shear walls and opening lintels. The program automatically generates internal result members from these wall objects, so they can be designed as members according to any standard in the Concrete Design add-on.
The Concrete Design add-on provides you with the option to perform the simplified fire resistance design according to EN 1992‑1‑2 for columns (Section 5.3.2) and beams (Section 5.6).
The following design checks are available for the simplified fire resistance design:
- Columns: Minimum cross-sectional dimensions for rectangular and circular sections according to Table 5.2a as well as Equation 5.7 for calculating time of fire exposure
- Beams: Minimum dimensions and center distances according to Table 5.5 and Table 5.6
You can determine the internal forces for the fire resistance design according to two methods.
- 1 Here, the internal forces of the accidental design situation are included directly into the design.
- 2 The internal forces of the design at normal temperature are reduced by the factor Eta,fi (ηfi), then used in the fire resistance design.
Furthermore, it is possible to modify the axis distance according to Eq. 5.5.
With the Concrete Design add-on, you can perform the fatigue design of members and surfaces according to EN 1992‑1‑1, Chapter 6.8.
For the fatigue design, you can optionally select two methods or design levels in the design configurations:
- Design Level 1: Simplified design according to 6.8.6 and 6.8.7(2): The simplified design is performed for frequent action combinations according to EN 1992‑1‑1, Chapter 6.8.6 (2), and EN 1990, Eq. (6.15b) with the traffic loads relevant in the serviceability state. A maximum stress range according to 6.8.6 is designed for the reinforcing steel. The concrete compressive stress is determined by means of the upper and lower allowable stress according to 6.8.7(2).
- Design Level 2: Design of damage equivalent stress acc. to 6.8.5 and 6.8.7(1) (simplified fatigue design): The design using damage equivalent stress ranges is performed for the fatigue combination according to EN 1992‑1‑1, Chapter 6.8.3, Eq. (6.69) with the specifically defined cyclic action Qfat.
