Evaluation of FEM based verification of bolted connections

Recent years have shown a growth of purpose-built software for the evaluation of connections in steel structures. In practice, such software packages are often used as replacements for the requirements stated in EN 1993-1-8 (Eurocode for steel structures – connections).

The requirements stated in EN 1993-1-8 are based on certain models and are validated with experiments. The mechanics of a FEM model relies on a different underlying modelling technique. As a result, the calculated design resistance of a connection may differ between methods. 

You are asked to make a comparison of the resistances of bolted connections according to EN 1993-1-8 and FEM software and test results. Depending on your interests, the work can further extend into:
    - Comparison of the calculated resistances with test results;
    - Compare the software with both the current EN 1993-1-8 as well as the draft for the revised version that is planned to be published in 2023;
    - What is the safety level of the FEM software (statistical analysis of tests and models);
    - Inclusion of welded connections in the study

Supervision and collaboration:
      - TU Eindhoven (contact: Dianne van Hove, b.w.e.m.v.hove@tue.nl)
      - TNO (contact: Sjors van Es, sjors.vanes@tno.nl)
      - Engineering firm: to be determined

The working location of the student (TUe, TNO or engineering firm) will be determined in consultation with student and supervisors.
