Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 3,   Pages 576-594 doi: 10.1007/s11709-021-0728-6

Abstract: Reinforced concrete beams consisting of both steel and glass-fiber-reinforced polymer rebars exhibitFor specimens that failed by fatigue shear, all the glass-fiber-reinforced polymer stirrups and somesteel stirrups fractured at the critical diagonal crack.The fatigue strength of the glass-fiber-reinforced polymer stirrups in the specimens was considerablytests on the glass-fiber-reinforced polymer bar, and the failure modes were different.
