摘要：Tensile mechanical properties of glass fiber reinforcement polymer (GFRP) bars under temperature effect is very important for engineering application. Based on three types of GFRP bars with different diameters under elevated and low temperature, change law of ultimate tensile strength and tensile elastic modulus in the temperature range of -20 °C to 300 °C were studied on GFRP bars. The results show that ultimate tensile strength decreases with the rise of temperature from -20 °C to 300 °C. Ultimate tensile strength and tensile elastic modulus decrease linearly below 100 °C. Above 100 °C, ultimate tensile strength decreases faster, temperature is higher. These
