A Study for Stress Distribution of the High-voltage Transmission Tower Under Wind Forces

The structural methodology in designing a transmission tower have been performed to assume a simple truss behavior. But there`re quite differences between a simple truss behavior and a real one. A suitable explanation for a structural stability can be expressed as a semi-rigid connection instead of the assumed hinged connection. This study proposes an alternative structural analysis modelling strategy for the transmission tower design. Proposed element models are truss element model, beam element model, and combined beam-truss element model. The static finite element analysis shows that there`s a moment distribution between a mainpost member and the other bracing member.
