Abstract
According the previous study, Tenaga Nasional Berhad (TNB) chosen wood, steel and
fiberglass as the substances for the cross arm of the transmission tower and is plagued
with the issue of torsional failure of the cross-arm part. So that, TNB has overlooked
the properties of Glass Fiber Reinforced Polymer (GFRP) in creating a better result. In
this paper,the torsional performances of five brands of GFRP tube which are Higoal,
VMCC, Electrius, Wagner and PUPI is tested. The objectives of this paper are to
determine the effect of thickness and fiber directions of GFRP tube to the torsion
strength, investigate the failure pattern of GFRP tube due to the torsional load and
evaluate the ultimate torsional strength and angle of twist of the GFRP tube. Total 10
specimens of 1m are test and subjected to combined effect of torsion and bending. A
loading frame and test set up are fabricated for applying combined torsion and bending.
Ultimate load, ultimate torsional moment, ultimate angle of twist and ultimate strain are
compared between different brand of GFRP tube.
