Abstract
Transmission towers are tall structures, usually a steel lattice tower, used to support an overhead power line. Usually, transmission towers are analyzed as frame-truss systems and the members are assumed to be pin-connected without explicitly considering the effects of joints on the behavior of the tower. In this research, a joint of the tower will be analyzed with the consideration of the joint detailing to investigate how it will affect the tower analysis. A static analysis using STAAD Pro was conducted to indicate the joint with the maximum stress. This joint has been explicitly analyzed in ANSYS using Finite Element Method. Three approaches were used in the software which are; simple plate model, bonded contact with no bolts and beam element bolts. Results from the explicit analysis show that stress values increased with joint details consideration. Some other approaches, which are more realistic than this research's approaches, can be considered to get more accurate results.
