Ferrocement, pioneered and perfected by Pierluigi Nervi, remains a subject of great interest in the field of structural engineering due to its remarkable mechanical properties, durability, and adaptability to complex architectural forms. In order to accurately assess its behaviour under load, both from a conservation and engineering point of view, reliable experimental methodologies and monitoring tools are essential. This research focuses on the design of a four-point bending test to evaluate the mechanical response of a full-scale (1:1) mock-up of the undulated ferrocement corner beam from "Torino Esposizioni Hall C", with particular emphasis on the preliminary structural analysis of the mock-up's response under bending and the calibration and optimization of Digital Image Correlation (DIC) as a surface deformation measurement technique.
