ABSTRACT
Nowadays, Fiber Reinforced Polymer (FRP) in civil engineering has been studied extensively, since it could solve the corrosion problem effectively. Besides the substantial resistance to corrosion CFRP has its superior material properties, such as high stiffness, high strength, light weight and fatigue resistance (Hollaway 2010, Ahn et al. 2014, Manalo et al. 2016, Hadi et al. 2016). However, the applications in civil engineering are limited due to the shortcoming as follows: (1) poor ductility, which means ideal ductility cannot be achieved in FRP-reinforced structures, the disastrous brittle failure for structures could be happened; (2) high initial cost, which means that the FRP material cannot apply in a low budget; (3) low strength utilization rate in the structural application (Rizkalla & Hassan 2002, You et al. 2015).
