Decarbonising ArcelorMittal’s Spanish operations21 July 2021
A memorandum of understanding (MoU) signed on 13 July 2021 between ArcelorMittal and the Spanish government demonstrates mutual intent to work together towards a decarbonised Spanish economy – a necessity for industries such as steel to successfully transition to carbon neutrality. As a result, new manufacturing processes at ArcelorMittal’s Spanish operations will include a new direct reduced iron (DRI) unit and electric arc furnace (EAF) installation in Gijón that will reduce carbon emissions at ArcelorMittal’s Spanish operations by approximately 50%. The DRI installation in Gijón will also enable ArcelorMittal Sestao to become the world’s first full-scale zero carbon emissions* steel plant.
Tâmega giga-battery: one of the largest hydroelectric projects developed in Europe in the last 25 years6 July 2021
In the north of Portugal, almost halfway between Porto and the Spanish town Ourense, the Tâmega River hydropower complex is being developed on the Tâmega River by Spanish power company Iberdrola Generación. Three dams and three hydroelectric plants are being constructed and are one of the largest constructions of this type in Europe in the last 25 years with a total investment cost of €1.5 billion.

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.
Why more and more architects are specifying carrier panel solutions
Offering aesthetic appeal, high performance, sustainability, and safety, carrier panel solutions are becoming increasingly popular with architects and specifiers seeking the perfect facade for their projects.
