The first test campaign for the Puente Carlos project in Peru took place in the Wind Tunnel of the Politecnico di Milano. The bridge, designed by Arenas & Asociados, Ingeniería de Diseño, together with Azize ingenieros, will be the first one crossing the Inambari River in the Madre de Dios district, creating new connections in the Amazonian area of Peru which are only accessible now using boat crossings.
The total lenght of this cable-stayed bridge will be 1260 m. with five towers and 235 m. long spans.
During a first wind tunnel campaign a 1:25 scaled sectional model has been tested to analyze the aerodynamics of the deck and the geometrical details such as guardrails and barriers. Then, a 1:100 scaled full bridge aeroelastic model has been reproduced in wind tunnel to verify the wind-structure interaction in the final design, including the construction stage in the worst case scenario. Tests were done in smooth flow condition, to check the stability of the bridge, and in turbulent flow condition simulating the natural wind at the site to check the aerodynamic response of the structure.
