Research on Tensile Mechanical Properties of GFRP Rebar after High Temperature
By tensile tests on GFRP rebar after high temperature, the change regularity and influent factor are analyzed. The results show that: With the temperature increasing, vitrification, carbonization, decomposition at high temperature test section of the GFRP rebar are aggravating , and their mechanical properties are deteriorating. At the same time, the limited tensile strength and ultimate tensile elastic modulus decreased in different degree.
