State-of-the-Art on Long-Span Bridge Aerodynamics in China
Abstract:The State-of-the-Art on long-span bridge aerodynamics in China is presented in this paper with an emphasis on three aspects: contributions in the development of aerodynamic theories, probability-based assessment method in evaluating bridge aerodynamics, and aerodynamic vibration control. The theoretical development discussed in this paper comprises the full-mode flutter analysis method, some new findings in flutter mechanism and stabilization as well as Computational Fluid Dynamics techniques and application. A series of probabilistic assessment approaches is then proposed and applied in wind induced vibration investigation including flutter instability, buffeting response and vortex-induced vibration. The final aspect focuses on the aerodynamic vibration control of long span bridges experienced in China.

Structural Engineering International (SEI), the quarterly Journal of IABSE, published since 1991, is the leading international journal of structural engineering dealing with all types of structures and materials. SEI offers its readers a unique blend of short profiles on recent structures, and longer, in-depth technical articles on research, development, design, construction and maintenance. Articles are written by practicing engineers and academia from around the world and reflect the high standards of IABSE. IABSE Peer Review stamps are given to papers that have passed through a highly selective review process and demonstrate a significant contribution to the state of structural engineering knowledge.To recognise contributions of the highest quality, an Outstanding Paper Award is presented each year.
