Comprehensive investigation into wind-induced aerodynamic and aeroelastic effects of large cooling towers

  • 摘要: 大型冷却塔作为空间薄壁高耸结构,结构风效应突出,在设计中风荷载属重要的控制因素。本文系统地介绍了同济大学结构风工程研究团队在冷却塔结构抗风方向取得的研究进展,涉及风荷载特征与统计、结构风效应试验与分析、整体结构多目标优化、灾害气候条件荷载与效应分析和全过程集成软件平台开发等5个方面,在冷却塔结构抗风问题中的风荷载、结构响应和试验模型设计等方面得出相应结论。

     

    Abstract: As typical thin-wall flexible structures, large cooling towers are of critical sensitivity to wind loads during its life-cycle. It's introduced systematically the research development of large cooling towers made by Tongji wind-resistance group during the past decades, including the study on statistic characteristics of the wind load from the full-scale observation, experiment and analysis of wind-induced structural responses, multi-objective structural optimization, the study on wind-induced loads and effects under disaster climates, the development of the self-developed whole process integration software platform, and so on. Some key problems in engineering application and fundamental investigation discovered during the development of large cooling towers in China have been resolved successfully.
