Description
Summary:The New Millennium Bridge in Lot 1 of the Amtae∼Aphae Fixed Link, is a FCM-anchored hybrid two-pylon cable stayed bridge consisting of its high (195m) and low (135m) pylon with two bundle cables in the back span and the pre-construction of the side span method during erection is considered to improve the aerodynamic stability. The design of the bridge for wind was carried out based on extensive numerical analyses and wind tunnel tests: extreme wind climate analysis for typhoon, dynamic wind load (buffeting) analysis, computational fluid dynamics (CFD) analysis and sectional model tests etc. A series of wind tunnel tests were performed to find the harmful windinduced vibrations: vortex-shedding, buffeting, and flutter. Moreover, some alternatives of the deck section were investigated to find an optimized one for a super long span bridge.
