Flooring

This master’s thesis by Francesco Profico was developed in ArcelorMittal’s R&D centre in Luxembourg. The focus of this thesis is the study of the plastic behaviour of composite dowel shear connectors. These constitute a relatively new typology of shear connectors in composite beams that offer an alternative to the well-established head-stud shear connectors. Composite dowels are made from interconnected steel obtained from a thermal cutting process and reinforced concrete dowels. To date, this new typology has been used in many bridge applications, and guidelines are present for designers in specific countries. Interest is now growing for building applications in which a plastic design for shear connection is often used.

Mechanical behaviour, assessment of maximum slip demand, and two building flooring solution case studies

The thesis also aims to present the topic of composite beams from a broader point of view, presenting overall mechanical behaviour. A numerical model to assess the maximum slip demand from the beam is presented using a strain limit analysis of the section.

In the annexes, two solutions for building flooring systems using composite dowels are presented. A complete calculation is presented, and parametric optimisation is done for both case studies.

This thesis was developed during an internship period in the ArcelorMittal R&D department and is promoted by the University of Trento, where it was presented at the master’s thesis defence in July 2022. The author, Francesco Profico, has now joined the Steligence® Engineering Team.

Analysis of the plastic slip capacity of steel-concrete composite dowel shear connectors: development of an analytical simplified model - a master's thesis by Francesco Profico

The Steel Construction Institute (SCI) has awarded its ‘SCI Assessed’ quality mark to ArcelorMittal’s Magnelis® ZM120 coating for corrosion protection. Magnelis® is a ZM (zinc-aluminium-magnesium) coating in accordance with EN 10346:2015.

SCI Assessed: independent quality verification

The established SCI Assessed quality mark is awarded after a manufacturers’ technical data has been independently verified by SCI.

SCI Assessed certification was awarded based on its independent review of the technical performance data associated with the corrosion protection of Magnelis® ZM120 coating on thin-gauge strip steel manufactured to BS EN 10346. The full details of the SCI assessment are available in SCI Report RT1892 v03.

Magnelis® ZM120 applications

Commonly used on cold formed sections for light steel framing, Magnelis® ZM120 is also widely used to manufacture cable trays, flooring systems, indoor ventilation equipment, ceilings, walls and partitions, racking systems, profiled members, and opened and closed profiles.

Magnelis® can be applied to an extensive scope of steel grades, including steels for cold forming and deep drawing applications, as well as structural and high strength, low alloy steels.

About SCI

The Steel Construction Institute has been a trusted, independent source of information and engineering expertise globally for over 30 years. SCI is a leading, independent provider of technical expertise and a disseminator of best practice to the steel construction sector.

Review of Magnelis® coating performance as corrosion protection by the Steel Construction Institute

ArcelorMittal took part in BAU, a major event for the construction and building industry, in Munich from 17-22 April, showcasing its latest high-performance steel products, XCarb® range of sustainable steels, and cooperations dedicated to construction.

Cooperations featuring XCarb® recycled and renewably produced steel

Two exciting new cooperations were announced during the event:

• ArcelorMittal has joined forces with BP2, a manufacturer of complete solutions for residential construction, to supply low carbon emissions steel for BP2’s latest product, the SOLROOF integrated photovoltaic roof.
• The VELUX Group has kickstarted cooperation with ArcelorMittal as part of its efforts to halve value chain emissions by 2030. The companies will now work together to lower the carbon footprint of the steels used in VELUX roof windows, aiming to reduce embedded CO2 by up to 70% (depending on the type of steel product used) compared with conventionally produced steel.

High-performance steel products

Flagship ArcelorMittal products presented at the event included:

• Granite® organic coated steels for building envelopes: available in more than 120 colours and textures and guaranteed for up to 40 years with Granite® HDXtreme
  
• Magnelis® metallic coated steel for facade substructures, solar mounting structures, cable trays, composite floors, and many more applications: resists corrosion three times better than regular galvanised steel
• Ondatherm Solar®: special roof panels for photovoltaic systems
• Cofraplus® 80 composite floor profiles: approved by building authorities as prefabricated steel floors and with a significantly lower carbon footprint compared to prefabricated concrete slabs
• high strength HISTAR® steels: providing cost and material savings
• weather-resistant Arcorox® steel grade: with natural corrosion protection and a long service life
