Research on Tensile Mechanical Properties of GFRP Rebar after High Temperature

Article Preview

Abstract:

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.
