Initial stiffness of integrally-formed GFRP T-joint in GFRP transmission tower

Scientific Reports
It is recognized that the semi-rigidity of the glass fiber reinforced polymer (GFRP) joint should be considered in the structural analysis of GFRP structures, because of the relatively small initial stiffness resulting from the intrinsic property of GFRP material. Regarding the integrally-formed GFRP T-joint in the GFRP transmission tower, the study of
