The invention relates to a vibration preventing hammer control method for vortex-induced wind vibration of an electric power tower frame steel tube member. A vibration preventing hammer comprises a hammer head and a steel stranded wire. The vibration preventing hammer control method comprises the following steps of determining the first-order natural vibration frequency of the steel tube member; determining the first-order natural vibration frequency of the vibration preventing hammer; matching the vibration frequency with the natural vibration frequency; arranging the vibration preventing hammer on the steel tube member. The vortex-induced wind vibration control effect of the steel tube member is remarkable by means of the vibration preventing hammer control method. The vibration preventing hammer is simple in selection calculation and is simply and conveniently installed and implemented on an existing tower frame structure, and the safety and economical efficiency of the structure can be improved.
