Rational arrangement of horizontal members for transmission towers considering the effects on the structural behaviors

초록

In this study, we investigated the importance of the structural design of horizontal members, which play a key role in maintaining the shape of transmission towers under torsion and distortion. The behavior of the structure owing to the role of the horizontal members was observed through various numerical analyses, including linear-static analysis, eigenvalue analysis, and geometric nonlinear and inelastic analyses under design load combinations. According to the analytical study, it was possible to maintain the torsional and buckling resistance of the transmission tower's main body even with a reduced number of horizontal members. Additionally, despite the decrease in horizontal members, the model achieved a similar load-carrying capacity to the existing design. Therefore, it is necessary to determine the appropriate position and number of horizontal members. © 2024 The Author(s)
