New R&D report SAFEBRICTILE: Standardization of Safety Assessment Procedures across Brittle to Ductile Failure Modes
ArcelorMittal R&D contributed to a research and development project related to Standardization of Safety Assessment Procedures across Brittle to Ductile Failure Modes. The objective for this research and development project, called SAFEBRICTILE, was to develop a procedure for the safety assessment of the various failure modes that are relevant for steel structures.
Several objectives to fulfil
The following objectives have been fulfilled within SAFEBRICTILE:
- Development of an objective and consistent assessment procedure for the safety assessment of the various failure modes that are relevant for steel structures. The unified procedure will cover: modes driven by plasticity + modes driven by stability + modes driven by fracture.
- Development of a more complex procedure in which newly developed design rules are defined by a pre-established safety factor.
- Reassessment of several rules in Eurocode 3 covering the failure modes treated in the project by applying the developed safety assessment procedures in order to check their compliance with the target failure probability.
- Proposal of new or improved design rules for cases where deviations from the target failure probability were observed.
- Conceptual development and further maintenance of a European database of steel properties resulting from experimental tests.
The report gives an overview of the reliability assessment of the Eurocode 3 design rules carried out within the project related to cross-sectional resistance; buckling resistance of columns, beams, and beam-columns; and weld resistance. It presents adjustments to these design rules proposed whenever it was necessary. It also establishes recommendations on the statistical distributions of the relevant basic variables for steel structures compiled in a European Database of Steel Properties that was also developed within the project.
