Simulation and Field Measurement of Wind-Induced Vibration Response Characteristics of the Lightning Rod

Journal of Physics: Conference Series
Abstract Studying the wind-induced vibration model and response characteristics of lightning rods is crucial for achieving their rational design and wind stability. To address the current shortcomings in considering on-site wind load characteristics and the lack of differentiated considerations in the design phase of lightning rods, it ...
