An Experimental Study on PC Concrete Beams with Steel Plate Embedded at the End of Beams

In this study, an experiment was conducted to evaluate the flexural performance of steel plate embedded beams, in which the steel plate was embedded at the end of the PC beam. From the factory manufacturing stage of the PC beam, the design process of each step in which the construction and finishing loads were applied at completion was reviewed to produce a 12 m span beam. A stud bolt was installed on the embedded steel plate at the end of the beam to ensure adhesion, and the experiment was performed using two specimens with embedded depths of 250 and 450 mm. When the load was removed owing to the pre-stressing effect of the strand, the displacement recovery rate averaged 87.0%, and the stiffness gradually increased even after yielding, exhibiting trilinear behavior that was approximately 1.8 times higher than that of the yield load when the load reached perfect plasticity. Even after the 250-mm test, which was the minimum depth of the steel plate embedment in the beam end, the joint remained in excellent condition, indicating that the bonded steel plate had a minimum depth of 250 mm.
