RPAS-Based Framework for Simplified Seismic Risk Assessment of Italian RC-Bridges
Existing reinforced concrete (RC) bridges that were designed in the decades between 1950 and 1990 exhibit inadequate structural safety with reference to both traffic loads and hazard conditions. Competent authorities are planning extensive inspections to collect data about these structures and to ad...
