INVESTIGATION ON THE AERODYNAMIC STABILITY OF LONG-SPAN SUSPENSION BRIDGES WITH 3D CABLE SYSTEM

摘要：

Based on a long-span suspension bridge-the Runyang Highway Bridge over the Yangtze River, three case bridges with different 3D cable systems are designed, structural dynamic characteristics and the aerodynamic stability are investigated numerically by 3D nonlinear aerostatic and aerodynamic analysis, and the cable system favorable to improve the aerodynamic stability of long-span suspension bridges is also discussed. The results show that as compared to the bridges with parallel and outward-inclined cable system, the suspension bridge with inward-inclined cable system has greater lateral bending and torsional frequencies, and also better aerodynamic stability, and seems more favorable for long-span suspension bridges.
