Dynamic response of self-supported power transmission tower subjected to wind action

A power transmission tower carries electrical transmission conductor at adequate distance from the ground. It must withstand all nature's forces besides its self-weight. In structural analysis, natural frequency, mode shape and damping ratio are used to define the structural dynamic properties...
