Due to their inherently flexible structural characteristics, bridges are particularly susceptible to wind-induced vibrations compared to other types of structures. As bridge spans become longer, wind loads play an increasingly critical role in the overall structural design, which is why accurate assessment of wind loads and aerodynamic stability under wind-induced vibration is essential. Wind tunnel testing for bridges is conducted to evaluate the aerodynamic behavior of individual components such as girders, pylons, and cables, or to assess the entire bridge system as a whole. In addition, wind tunnel tests may also be carried out for secondary elements such as guardrails, obstacles, or road signage.

Full Bridge Model Test
The aerodynamic behavior of a bridge is influenced by the combined dynamic characteristics of the deck, pylons, cables, and surrounding terrain. Therefore, full bridge model testing is essential for accurate analysis, especially during the construction phase when the dynamic properties of the structure are constantly changing, making three-dimensional aerodynamic stability assessment crucial.

Buffeting & Flutter Analysis
Buffeting refers to random vibrations induced by the turbulent components of approaching wind flow, while flutter is an aerodynamic instability caused by a positive feedback loop between structural vibrations and wind-induced forces. Our role is to thoroughly analyze these vibrations and provide appropriate engineering solutions.
