Abstract
The dynamic response analysis of a transmission angle tower subjected to wind excitations is actively carried out in this study. The structural model is constructed based on finite element approach with the aiding of commercial package ANSYS. The equation of motion of the transmission tower-line system under wind excitations is established. The dynamic wind loading are applied on the tower-line system to examine the structural responses. The deformation and stresses distribution of the transmission angle tower are computed to explore the structural performance. The made observations indicate that the peak stresses of some members are large than the permitted yielding stresses of steel material.
