About one hundred people including academics, students and professionals such as engineers, geologists, surveyors and architects participated in the conference "Degradation and seismic vulnerability of existing bridges and viaducts" organized by the degree course in Civil Engineering of the University of the Republic of San Marino . On the calendar yesterday, Thursday 4 April, the initiative saw Luigino Dezi, professor at the Marche Polytechnic University, take the chair in the university headquarters of the World Trade Center in Dogana.
"The numerous structural failures of bridges and overpasses that have occurred in recent years have highlighted the fragility of the Italian road infrastructure system", explained the academic. “Most of them have been built for more than 50 years and tens of thousands of bridges have exceeded the lifespan for which they were designed. It is a systemic fragility attributable on the one hand to maintenance shortcomings and the age of the materials, on the other to a design based on principles that are no longer current and unable to take into account the causes of risk that today form the basis of technical standards . However, the inadequacy of the resources necessary for the interventions represents the hardest of the obstacles to overcome in order to implement the measures necessary for risk mitigation".
