摘要
主要介绍同济大学土木工程防灾国家重点实验室在国家自然科学基金重大项目资助下进行的题为“特大跨度桥梁的气动参数识别、风振及控制理论”的专题研究中所取得的主要成果 ,包括气动参数识别 ,非线性颤、抖振分析 ,桥梁数值风洞 ,颤振概率评价以及等效风荷载等方面的内容。这些成果已在许多大跨度桥梁 ,如江阴长江大桥、润扬长江大桥、南京长江二桥、苏通长江大桥和南京长江三桥中得到应用 ,显示出理论意义和实用价值。
Recent advances in research on aerodynamics of extra long span bridges are reviewed in the paper. It is based on the work done by the State Key Laboratory for Disaster Reduction in Civil Engineering in Tongji University. Many topics of wind engineering are discussed at detail. It is concerned on the wind induced vibration, flutter, and buffeting. It is found that the wind tunnel test is substituted by the computational fluid dynamics. It is so called numerical wind tunnel. The results are used in the recent completed and designed bridges.
