Wind-induced vibration coefficient is a key parameter in the structural design of transmission towers.However,the calculation formulas of wind-induced vibration coefficient in design codes at home and abroad are complicated.Based on the inertia force method,the calculation method of wind-induced vibration coefficient of transmission towers is deduced and optimized,and the influencing parameters are analyzed.The research results simplify the calculation process and are accurate,which provides a more efficient new idea for the calculation of windinduced vibration coefficient of transmission towers.
