Experimental study of along-/across-wind aeroelastic response coupling in a tall square tower

Key Points

• The aeroelastic response of a tall square tower is significantly influenced by wind load variations—particularly along- and across-wind effects.
• Analysis showed that coupled responses can lead to increased vibration levels under specific wind conditions and configurations.
• Observational analysis across multiple wind speeds and angles was conducted to assess structural dynamics during experimentation.
• Findings highlight the need for further investigation of coupled wind effects in tower design, suggesting potential improvements in safety and performance.
