摘要
选取配筋为FRP筋的混凝土梁进行研究,通过4组AFRP和5组CFRP试验梁对其受弯性能进行研究,计算出其开裂弯矩和屈服弯矩,并与试验数据进行对比。研究表明:对于开裂弯矩及屈服弯矩,计算值与试验值之比的平均值分别为1.08和1.03,标准差分别为0.14和0.23,整体吻合较好,可以采用该方法对FRP筋混凝土梁进行屈服荷载的计算。
This paper choose concrete beams reinforced with Fibre Reinforced Polymer bars to be studied. There are 4 AFRP and 5 CFRP test beams to study their flexural behavior. Their cracking bending moment and yield bending moment are calculated and compared with the test datas. Tile results show that good agreement between prediction results and test results for cracking bending moment and yield bending moment is achieved with an average ratio of test results to predicted results being 1.08 and 1.03, the standard deviation being 0.14 and 0.23. Consequently the calculation method absolutely can be used for cracking bending moment and yield bending moment calculation in this test data of concrete beams reinforced with FRP bars.
