This paper will study the feasibility of building a transmission tower from a composite material, E-glass and Vinylester. The tower was fabricated using a fabrication process called pultrusion. Also instead of using the conventional fastener method to join the cross members to the leg members, the design team utilized a slip joint that was developed by Goldsworthy Engineering
The lamina of the leg member and the cross bracing were tested and compared with two analytical failure criteria, Yeh-Stratton Criterion and Quadratic (strain space) Criterion. In addition to ply failure analysis a full scale tower tests were performed at Electrical and Power Research Institute.
