울산대교(단경간 장대 현수교) 내풍안정성 검토

The wind-resistant design is the most important issue for the feasibility of the Ulsan Grand Bridge (single span suspension bridge) with the center span of 1,150m. This paper investigates the aerodynamic stability of the bridge focusing on the bi-modal section model tests and the multi-modal aeroelastic analyses. As a result, it is confirmed that the Ulsan Grand Bridge is aerodynamically stable against coupled flutter, buffeting, and vortex-induced vibration.
