Introduction  Transmission towers are crucial infrastructure in power systems, and their wind-induced collapse can cause significant losses to power systems. To find solutions to prevent wind-induced collapse of transmission towers, it is necessary to investigate the causes, contributing factors, and processes of wind-induced collapse.

  Method  Research results on wind-induced collapse of transmission towers were reviewed from the perspectives of accident analysis, full-scale tests, wind tunnel tests, and numerical simulations. The relevant research results were analyzed and summarized, and recommendations for subsequent research were provided.

  Result  The investigation revealed that the factors contributing to the wind-induced collapse of transmission towers include the presence of weak members in the tower body, defects in the calculation of wind loads on transmission lines in the code, and extreme wind loads not considered in the code.

  Conclusion  It is recommended to research extreme wind load models, the impact of crosswind and torsional wind loads, accurate models of single tower and tower line systems, and improvement of relevant regulations in the code.
