摘　　要：通过GFRP(玻璃纤维增强塑料)筋混凝土和素混凝土标准立方体抗压强度试验表明,GFRP筋混凝土的力学性能要优于素混凝土;通过ANSYS(有限元分析软件)模拟的不同GFRP筋用量对混凝土应力-应变的影响,表明GFRP筋用量的增多能延长混凝土的使用寿命;用ANSYS有限元对混凝土立方体加-卸载循环过程进行了数值模拟,结果表明,加入GFRP筋后的混凝土抗疲劳性优于素混凝土。模拟的结果和实验结果都可以得出相同的结论。The standard cube compression strength tests of GFRP（Glass Fiber Reinforced Plastic） rein- forced concrete and ordinary concrete show that the mechanical properties of GFRP reinforced concrete is better than plain concrete. The influence of the amount of GFRP on the stress-strain of concrete is simula- ted by ANSYS（finite element analysis software）. The simulation results indicate that the increase of the a- mount of GFRP could prolong the service life of concrete. The add-unload cycle process of concrete cubes is simulated by ANSYS finite element method, the results of which show that the fatigue resistance of con crete after adding GFRP bars is stronger than that of plain concrete. The same conclusion can be drawn from the simulated results and the experimental results.
