A recent study by the Universitat Politècnica de València, Spain, highlights the advantages of constructing buildings with hybrid steel beams. They represent an innovation, by combining high-strength steel in the flanges with medium-strength steel in the core. This makes the structures lighter and less costly economically, without sacrificing performance.
In addition, hybrid beams reduce material requirements and structural weight compared to conventional beams. The reduction in transport and installation costs is directly proportional. Consequently, the CO₂ emissions associated with the construction that uses them are lower, so they represent, finally, a clear advance in sustainability.

he Politècnica’s research analysed 128 previous studies, with the aim of systematising existing knowledge on the optimal proportions between different steel grades and maximising the efficiency of the beams. The study also addressed key challenges, such as design for extreme loads. It used the integration of artificial intelligence and advanced optimisation techniques.

Hybrid beams not only contribute to more efficient and environmentally friendly development, but also bring about a transformation in the design and construction of infrastructure. This development reinforces the sector’s commitment to innovation and sustainability.
