GRIFFON is the intelligent system developed by iWIM to improve structural monitoring<\/strong> of bridges and viaducts. The project was created together with the DICATAM Department of the University of Brescia, with a specific goal: to combine dynamic weighing<\/strong>(weigh-in-motion<\/strong>) of vehicles with continuous measurement of structural deformations. <\/p>

This system directly links fiber-optic sensors<\/strong>, installed on the deck, with WIM modules that detect weight, position and speed of heavy vehicles. Each step is then associated with the actual response data of the structure. The result? Accurate, continuous and reliable structural monitoring<\/strong> that allows action to be taken before critical problems arise. <\/p>

Through this integration, GRIFFON supports predictive maintenance of bridges<\/strong>. Operators can plan interventions in a targeted manner, save costs and increase the service life of the works. In addition, the platform automatically generates a digital twin of the infrastructure<\/strong>, updated with actual transit and measurement data. This digital twin makes it possible to simulate the behavior of the structure and predict any critical issues. <\/p>

GRIFFON has already proven its effectiveness. On the South Bypass bridge in Brescia, it has monitored thousands of vehicles every day. It recorded overloads in real time and provided accurate deformation curves. All this has improved operational management and increased bridge safety<\/strong>. <\/p>

In summary, GRIFFON offers a complete solution: it integrates structural monitoring<\/strong>, dynamic weighing<\/strong>, weigh-in-motion<\/strong>, fiber-optic sensors<\/strong> and digital twin infrastructure<\/strong> into one system. It is the ideal tool for those who want to make infrastructure safer, more efficient and ready for the challenges of the future. <\/p>

GRIFFON is a continuous structural monitoring<\/b> system that natively combines dynamic vehicle weighing<\/b>. The modular architecture involves optical sensors distributed along beams, supports, and piers, while weigh-in-motion scales installed on the deck capture the acting load in real time. In this way, GRIFFON’s structural monitoring<\/b> seamlessly links cause and effect, providing the operator with comprehensive data 24\/7. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The real innovation lies in the tight integration of structural monitoring (SHM) and dynamic weighing (WIM). With GRIFFON, each and every vehicular transit is tracked: the measured weight is immediately correlated with the recorded deformation, slope, and vibration, increasing the accuracy of structural monitoring and reducing uncertainties in prediction models. This results in: <\/p>

Optical sensors provide robust structural monitoring<\/b>: no local power supply, EMI immunity and durability > 20 years. Strain gauges measure micro-deformations with 0.1 \u03bc\u03b5 resolution, while optical accelerometers and inclinometers provide accurate data to enrich structural monitoring<\/b> with dynamic parameters. An arrow laser completes the picture by providing millimeter measurements of deck deflection. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    In the pilot project, the combination of dynamic weighing and structural monitoring<\/b> identified an exceptional 101 t transport that generated a 13.64 mm arrow. Comparison with the FEM model, updated with structural monitoring<\/b> data, showed a deviation of less than 3 percent, validating the sensory configuration.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
