Abstract
In order to improve the durability of Bridges,the failure mode,ultimate load and shear resistance of carbon fiber reinforced beams under different loading conditions were analyzed through three-point bending tests.The results show that the damage effect of alternating load on the specimen beam is more significant.The mid-span deflection of the reinforced beam increases with the increase of load.When the load exceeds 30 kN,the deflection increases faster.The mid-span deflection under static load and alternating load is greater than that under no-load.The yield strain increases with the increase of load,and the yield strain of the beam under no-load is higher than that under static load and alternating load.关键词
