Eurocodes (EC)

Professional Structural Software for Eurocodes

Eurocodes

Eurocodes (EC) are a set of harmonized technical rules for the structural design of construction works in the European Union.

Currently, there are 10 Eurocodes (EC 0 to EC 9 in the standards EN 1990 to EN 1999). These are further subdivided. Eurocode consists of a total of 58 standard parts.

In addition, standard committees of all member states create a National Annex (NA) to each Eurocode covering primarily the nationally determined parameters, such as partial safety factors.

Eurocode Parts

Eurocode 0: Basis
Eurocode 1: Actions
Eurocode 2: Concrete Structures
Eurocode 3: Steel Structures
Eurocode 4: Composite Structures
Eurocode 5: Timber 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 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

Splitting Surface

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. In the depicted dialog box, you can define how often and at which distance the respective surface is to be divided along the boundary lines A and C as well as B and D.

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

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.

001389 Technical Article Concrete Structures RF-PUNCH Pro Add-on Modules Eurocode 2

Punching Shear Design According to Eurocode 2 in RFEM

For the structural components consisting of slabs, it is necessary to perform shear design on the locations with concentrated load introduction, applying the punching shear design rules according to Chap. 6.4 of EN 1992-1-1 [1]. The concentrated load introduction is present on the individual locations, for example by columns, concentrated load, or nodal supports. In addition, the end of linear load introduction on slabs is also regarded as the concentrated load introduction. This may include wall ends, wall corners, and ends or corners of line loads and line supports. You can perform the punching shear design for floor slabs or foundations, considering the available existing plate topology about the designed node of punching shear. The punching shear design according to EN 1992-1-1 checks that the acting shear force vEd does not exceed the resistance vRd.

Design of Tapered Single-Span Beam According to Eurocode 3
The following article describes the design of a single-span beam subjected to bending and compression, which is performed according to EN 1993-1-1 in the RF-/STEEL EC3 add-on module. Since the beam is modeled with a tapered cross-section, thus not a uniform structural component, the design must be performed either according to General Method in compliance with Chap. 6.3.4 of EN 1993-1-1, or according to the second-order analysis. Both options will be explained and compared, and for the calculation according to the second-order analysis, there is an additional design format using Partial Internal Forces Method (PIFM) available. Therefore, the design is divided into three steps:
1. Design according to Chap. 6.3.4 of EN 1993-1-1 (General Method)
2. Design according to the second-order analysis, elastic (warping torsion analysis)
3. Design according to the second-order analysis, plastic (warping torsion analysis and Partial Internal Forces Method)
