BRIDGES

Suspension or cable-stayed bridges are very sensitive to the effects of wind. In addition to static forces, the increasing length of bridges since the 1940s has led to the appearance of dynamic phenomena, as in the famous Tacoma Narrows bridge event. This event initiated the systematic study of bridge aeroelasticity.

The IDR-UPM facilities allow the study of both static and aeroelastic effects caused by wind. They also allow the study of the flow perceived by bridge users or loads on bridge users (e.g. vehicles). The experimental set-up for aeroelastic tests allows the study of vibrational instabilities induced by vortex, flutter, gallop and pitch and roll. In addition, the models are fabricated in such a way that different configurations can be tested, e.g., in construction or in service, or with different types of protective barriers.
