Laser cutting is a relatively new technology in the steel structures field if compared with other process like welding. The complexity of physical mechanisms dominant the laser cutting process plays a fundamental role on the alteration of material properties of the heat affected zone and consequently on the structural response of elements subjected to high‐cycle fatigue applications. Moreover, in the last years an important evolution was observed in steel structures execution through the standard EN 1090 that introduced both the concept of execution class and minimum requirements for structural elements. The limitations of the local hardness HV10 on the cutting surface, imposed by the standard EN 1090 for high‐cycle fatigue applications, certainly is an important parameter but it is not enough to explain the behaviour of structural elements.

The proposed study is focused on the investigation of correlations between …
