Kraków railway bridge: a titanic and Luxembourgish construction
8 January 2024ArcelorMittal contributed to one of the largest Polish railway projects of the decade: the reconstruction of the E-30 railway corridor in Kraków and the modernisation of several stations connecting two districts of Kraków.
Project newsTTV (Thickness Toughness Validator): a tool for validating the selected toughness subgrade for thickness and design conditions based on EN 1993-1-10
14 September 2023TTV (Thickness Toughness Validator) is a tool developed internally by ArcelorMittal Steligence® Engineering. It is a simple tool for validating the selection of toughness subgrades according to the recommendations and requirements of the EN 1993-1-10 standard. This standard provides design guidance for the selection of steel for fracture toughness, imposing maximum detail thicknesses depending on material, temperature, and load level. The simplified method (EN 1993-1-10, Clause 2.3) is based on a simple table check. As it is general, it is based on safe assumptions that may not always correspond to specific project specifications. The advanced method (EN 1993-1-10, Clause 2.4), based on more advanced fracture mechanics methods, has therefore been implemented in order to perform a more specific check to deliver more advanced results. This tool is entirely based on Eurocode background methods and their application. As such, the advanced method will deliver the same results as the tables of the simplified method if the same assumptions are introduced. The user guide and validation examples are provided in the tool’s download folder.

Kraków railway bridge: a titanic and Luxembourgish construction
ArcelorMittal contributed to one of the largest Polish railway projects of the decade: the reconstruction of the E-30 railway corridor in Kraków and the modernisation of several stations connecting two districts of Kraków.
The project
Started in 2017, work on the E-30 railway corridor includes the total reconstruction of a railway bridge over Poland's largest river - the Vistula - in the centre of Kraków.
Initially, a simple partial renovation was planned with the addition of two additional bridges on either side of the existing deck, but after technical and financial analyses, it was decided to construct a complete set of three new bridges. In 2020, the City of Kraków and the investor, PKP PLK S.A., agreed to extend the scope of works by installing a cycle and pedestrian path on the outer deck, leading to a change in the design and an increase in the width of the bridge.
HISTAR® for extraordinary constructions
ArcelorMittal and its beam finishing centre (BFC-LPL) based in Niederkorn, Luxembourg supplied 1300 tonnes of HISTAR® 460 and was commissioned to carry out the cutting, bending, and chamfering of the beams for the preparation of the welds on the bridge site. With a total length of 229 metres, the largest reinforced concrete slab covers 1200 m3, and its pouring took twenty hours continuously. A unique feature of the solution included the use of HD 400 sections (in various sizes) in HISTAR® 460 for the arch elements on which the entire bridge is suspended. The use of heavy-duty HD profiles in this unique project significantly reduced the volume of material required and accelerated the on-site assembly process.
Today, this bridge is the longest and thinnest railway bridge of its kind ever built in Europe. After the first side of the bridge was put into service in May 2020, the second double-track bridge (the most central) opened in June 2022. It was in May 2023 that the third bridge was opened for rail traffic.

The aim of this tool is to disseminate structural design knowledge and techniques for a subject that is often less known to designers. With TTV, the process of verifying steel details according to toughness requirements will be easier and will speed up workflow. Moreover, TTV includes advanced methods permitted by design standards, giving the user additional choices for verification methods.

Successes for sustainable construction at BAU
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
