    Exciting insights into the work of the DBV working group “So 2 months ago

    On November 7, Prof. Dr.-Ing. Frank Fingerloos from Deutsche Beton- und Bautechnik-Verein E.V. and Dr.-Ing. Elisa Lafuente Hernández from Krätzig & Partner Ingenieurgesellschaft für Bautechnik mbH presented the work of the DBV working group, which contributes significantly to the EvaDAT platform, at the 29th Dresden Structural Engineering Seminar.

    In their presentation on “Software for Structural Analysis” as a dialogue platform for software producers and structural engineers, they provided insights into their current work results:

    • Development of 11 EvaDAT evaluation examples to date
    • Participation in the standard interpretation of the concrete working line for low modulus of elasticity (solution to the numerical problem was included in DAfStb issue 600-1 as explanations to 3.1.5)
    • Technical articles for DBV circulars, e.g., on determining the temperature distribution in the concrete cross-section and calculating the buckling stability of prestressed precast beams
    • Practical experience of an engineering firm with the EvaDAT example 0040-D-DBV-AK software “Influence of creep on the design of slender spun concrete columns according to the general method”

    A big thank you to Prof. Dr.-Ing. Frank Fingerloos and Dr.-Ing. Elisa Lafuente Hernández for their excellent presentation and to the entire DBV working group for their commitment to jointly advancing the future of software-supported structural design!

    Ingenieurakademie West supports EvaDAT - platform can contin 1 year ago

    The first discussion took place at the beginning of the year, and in October the time had come: We are pleased to announce that the Ingenieurakademie West is now also supporting the EvaDAT platform to a special extent by placing an advertisement!

    Our intention to make the platform available to everyone free of charge and to finance it through advertisements has so far meant that the platform is in serious financial difficulties and is largely financed privately by our management. The advertisement from the Ingenieurakademie West gives us some breathing space, so that the platform can continue to exist for the time being and we can focus again on publicizing and disseminating the platform again.

    On behalf of all users we say: THANK YOU dear Ingenieurakademie West for your support!!!

    We would like to thank everyone who has supported us with a 1 year ago

    As we continue to provide the evaluation database free of charge, financial support through advertisements is vital - every amount helps.

EvaDAT - Quality assurance according to VDI 6201 for software-based structural analysis and design

How can it be ensured that what is numerically calculated with software programs and for which "beautiful colorful pictures" are displayed in the result presentations is actually correct?

On the software production side, this requires clarification of: Does the program calculate correctly? What is behind it, which theories are used? On the side of the software usage one must ask: Is the program suitable for the individual task at all? Is the user using the program correctly? Are the subtleties of the program known?

EvaDAT is the answer!

On the platform EvaDAT neutral evaluation examples based on the guideline "VDI 6201 Software-based structural analysis" are provided, which can be used to check your own results.

The basic idea of EvaDAT is that the evaluation examples are posted via the expert public: via the platform, three independent users with three different software programmes come together, each of which processes an example and, after discussion, possibly revision and evaluation of the results, releases this example, i.e. "qualifies" it. The examples should emphasise one feature in particular (e.g. the shear component of thick components is taken into account) so that differences remain identifiable. In terms of character, everything can be included: from simple FEM benchmarks to discussion-worthy questions from practice. From the student to the proven expert in a field, everyone can extract valuable content and programme-specific information for themselves.

Use the posted evaluation examples for your own quality assurance. A selection of essential advantages that EvaDAT offers you are summarised under About EvaDAT/Why EvaDAT.

EvaDAT - The platform for the implementation of the guideline "VDI 6201 Software-based structural analysis"

In the construction industry, there will be no TÜV-like authority due to the diverse calculation paths; the responsibility, warranty and liability always remain with the software user. Therefore, according to VDI 6201, the user must be given neutral (!) evaluation examples with the help of which he can determine whether he achieves comparable results with his own software. The guideline defines the form and content of the examples and 5 sample examples are given. Further examples are to be collected in a database over time. This database is realised by EvaDAT!

Part 1 Fundamentals, requirements, modeling and Part 2 Verification examples have been published for the guideline.

Research project: Conception and development of a standardized evaluation database for software-based structural analysis according to VDI 6201 for the use of structural analysis and design software in BIM-based process chains

The conceptual design and initial set-up of the database was carried out in a research project within the framework of the "Zukunft Bau" research initiative of the Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) of the Federal Ministry of Transport, Building and Urban Affairs at the University of Wuppertal from 2016 to 2019. The project was supported by 18 well-known project partners from the field.

Are you curious?

The use of the EvaDAT platform is free of charge. In order to have unrestricted access to all content, you must be registered and logged in. If you enter your company in your profile, you can also show the outside world that your company is involved in quality assurance in software-based structural analysis according to VDI 6201.

An explanation of the procedure for using existing evaluation examples as well as instructions for setting new evaluation examples can be found at About EvaDAT/How it works.
