The invention relates to a cement electric pole equivalent wind load loading device and an experiment method. The experiment method comprises steps of calculating the cement electric pole wind load, wherein the cement electric pole wind load includes a cement rod top lead wind load, an accessory wind load like the cross arm on the top of a cement rod , and a cement rod body wind load, and the wind load of each part is obtained through considering the wind-facing area, the wind pressure value, the shape coefficient, etc, obtaining an equivalent loading force amplitude on the basis of the fact that the bending moment on the cement electric pole by the loading force is equivalent to the bending moment on the cement electric pole by the wind load, taking the frequency point corresponding to the maximum amplitude value in the practical dynamic wind load frequency spectrum curve as the frequency of the equivalent loading force so as to determine the amplitude value and the frequency, and determining the time domain changing function of the equivalent loading force. The invention can provide a loading experiment method for generating a dynamic force equivalent with a certain typhoon level, which can realize the detection and estimation on the wind resistance of the cement electric pole and can further extract and improve the basic construction rule.
