|Summary||An extensive research project is currently being carried out at the University of Manitoba, Canada, to develop lightweight glass fiber-reinforced plastic (GFRP) poles for use in transmission and distribution lines. In this paper, results from tests involving full-scale tapered GFRP poles with hollow a circular cross-section subjected to cantilever bending are presented. The filament winding process was employed to produce those poles using vinylester resin reinforced with E-glass fibers. Twelve bending tests were conducted on full-scale poles up to failure. Test parameters included fiber orientation and number of layers. Extensive theoretical work preceded the test program and a theoretical model was developed. The results to-date indicate that the developed theoretical model can predict quite well the ultimate capacity and behavior performance of GFRP poles.
