我国大跨度缆索承重桥梁的空气动力性能研究

Aerodynamic Studies of Long-span Cable-supported Bridges in China

本文介绍了我国大跨度桥梁空气动力性能方面的研究情况。以同济大学土木工程防灾国家重点实验室所从事的桥架空气动力性能的理论和试验研究工作中的几个主要方面为重点,介绍最新进展,其中包括非线性颤振的频域分析,颤振分析的全模态技术,基于计算流体动力学的数值风洞等研究课题。

The aerodynamic studies of long-span bridges in China are introduced. The authors focus on some main points in theoretical and experimental research on bridge aerodynamics at the State Key Laboratory for Disaster Reduction in Civil Engineering (SKLDRCE) , Tongji University. Recent new developments are introduced, including nonlinear flutter analysis in frequency domain, full mode technique for flutter analysis, establishing of numerical wind tunnels applying CFD technique and current researches of bridge aerodynamics financially supported by Chinese National Science Foundation. Some aerodynamic considerations in designing several long-span bridges are also mentioned.
