Concrete beams with spliced reinforcement were subjected to low-amplitude high-cycle sinusoidal loads. Threaded coupler-type splices were utilized with the 16 mm high-yield reinforcing bars. During the tests the maximum stress caused by the sinusoidal load in the bottom reinforcement was kept constant at a value of 242 MPa for all beams. This stress level corresponded to the stress in the bottom reinforcement due to the service load. The minimum stress was varied to obtain various stress ranges. It can be concluded that the threaded couplers In the 16 mm reinforcing bars as used In the reinforced concrete test beams, subjected to a harmonious repetitive loading, have no detrimental effect on the fatigue resistance of the beam.
