The paper is the first step towards the aerodynamic analysis of slender structures to wind actions. By Rayleigh-Ritz technique and Lagrange equation, the paper describes the vibrationof a continuous structure though a system of ordinary differential equations in a way more familiar with structural analysts. This vibration method will be applied to antenna pole for dynamic analysis.
