- Structural Design: GPA
In accordance with the specific category bridge regulations, an existing bridge over the Ticino River has been structurally reinforced and adjusted for load. It was originally built in the 1960s with a reinforced concrete structure. The project was preceded by a series of investigative surveys to acquire data concerning the structural condition of the bridge; in particular: tests with sclerometer, tests on materials, sampling, ultrasonic micro-seismic tests, static load test and dynamic testing were carried out. The project work involves: • reinforcement of the beams adding steel bars and concrete; • increasing the load-bearing capacity of the bridge under seismic actions adding inox steel bars; • increasing the load-bearing capacity of the bridge under seismic actions introducing Bumpers in the joints;• fibre-reinforced polymer (FRP) strengthening of the reinforced concrete structural elements.
