BUILDING OF A COMPOSITE TRANSMISSION TOWER

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