Abstract: In this paper, experimental investigation of laced reinforced concrete beams (LRC) under fatigue loading is produced. Six simply supported beams are subjected to high loading frequency (10 Hz) with displacement control to study the effect of lacing reinforcement on the fatigue performance of LRC beams. Three parameters are used in fatigue test, which are lacing bar diameter (6mm and 8mm), lacing bar inclination to beam axis (30, 45 and 60), and lacing steel ratio. Mid-span deflections for LRC beams are compared. From comparison results, it is observed that the deflection is decreased with increasing of lacing bar diameter, lacing bar inclination and lacing steel ratio.
