The particular characteristics of structural steel offer optimal solutions that satisfy architectural, engineering, and economic aspects.
ArcelorMittal Europe’s trademark steels are HISTAR® and FRITENAR® - structural steel grades combining high strength, good toughness, and superior weldability, exceeding requirements and offering supplementary guarantees.
The solution for lightweight, long-spanning structural elements is to implement the cellular ACB® and Angelina® beams. With their circular and sinusoidal web openings, they elegantly combine function with flexibility.
CoSFB (Composite slim floor beams) integrates the advantages of composite design with traditional slim floor construction.

Economical and safe design approaches for steel sheet piling structures in highly seismic zones
Widely used for the construction of a variety of structures such as quay walls and breakwaters in harbours, bank reinforcements on rivers and canals, underpasses, as well as global hazard protection schemes, sheet piles have proven their performance in seismic areas in many countries around the globe.Chile, the country that has suffered the strongest earthquakes in recorded history, provides an excellent example: Whereas its concrete-based ports have been severely damaged, the Port of Mejillones, constructed in 2003 using an HZ®/AZ® combined wall for the quay wall and AS 500 straight web sheet piles for the breakwater, has not suffered any damage throughout many heavy earthquakes with magnitudes of up to 7.7. This is the perfect example of the effectiveness of flexible sheet pile structures under extreme seismic conditions.Nevertheless, a certain reluctance to use sheet piles in seismic areas remains common among some designers. This concern may come from their experience of conventional design methods which do not favour flexible walls in seismic areas. These design methods are usually comprised of pseudo-static calculations using the Mononobe-Okabe theory (1931).Numerical studies and physical experiments (centrifuge testing) have shown that these conventional methods of design are overestimating the loads on retaining walls - especially in the case of flexible walls. Although EN 1998-5 allows for a reduction of the seismic action depending on the acceptable displacements (reduction factor “r”), this only applies to gravity walls and not to anchored walls such as sheet pile walls, despite their inherent ductility.Today, powerful design tools using Finite Element Modelling (FEM) allow for dynamic calculations that can accurately predict the behaviour of the retaining walls undergoing different seismic loadings, including internal forces, deformations, increases in pore water pressures, and expected modes of failure.Article
Iconic. A piece of art. The symbol of Paris. The Eiffel Tower is the best known example worldwide of structural steel architecture. The design and dimensioning of modern buildings requires careful consideration of many factors such as technical requirements including building physics, architecture, and cost-effectiveness.
ArcelorMittal also offers a number of pre-design tools in order to support engineers in the use and calculation of our range of steel products and solutions. These free tools cover various design aspects of steel and composite structures in accordance with Eurocodes (beams, columns, castellated beams, slim floor solutions, steel grades, connections, etc.), different performances (e.g. fire & seismic calculations, life cycle assessment, and cost estimation), and construction types.
Our technical team is always at your disposal and will gladly assist you by answering all of your questions in order to provide you with the most beneficial offer.
