This paper presents a review of the creep behavior of fiber reinforced polymer. Fiber reinforced polymer composites are utilized in transmission line as an alternative to cross arm structure in replacing the conversational cross arm, due to a good potential of fiber reinforced polymer widely used with well-known advantages mainly related to easy manufacturing, lightweight, moldability, high-quality surface finishes and optimal mechanical properties. Creep behavior is fundamental for the element to withstand loads in maximum period. Due to extreme creep deformation, the impaired structure may happen or even result in structural collapse. Creep was measured by flexural creep test, finite element method and numerical method by using Ansys. A creep behavior was investigated on Glass Fiber Reinforced Polymer (GFRP) as the result after 6 and 14 months, Young's modulus composites were reduced to 20%. Meanwhile, creep behavior of GFRP pultruded flexural member show shear stiffness after 50 years with 22% to 43% with average reduction of effective instantaneous flexural and higher creepocity because of the shear deformation instead of bending counterpart. Finally, a creep study on GFRP girder show an increment of instantaneous deflection up to 40% after five months it is confirming the potential of GFRP in structural industries.
