EFFECTS OF SHEAR REINFORCEMENT ON STRUCTURAL PERFORMANCE OF RC BEAM WITH HORIZONTAL JOINT AND SHEAR TRANSFER IN THE CONNECTION

摘要

The object of this paper is to make clear the structural performance of RC beam with horizontal joint, and the shear transfer mechanism and the shearu0012 displacement behavior at the interface. The experimental study for thirty-six specimens whose parameters were the amount and the strength of shear reinforcement bars, and shear span ratio of the beam, and the loading method was carried out. The results are as followed. The shear strength, flexural strength, and stiffness of the specimens slipped at the interface were lower than those of the monolithic specimens. The shear transfer mechanism and the shear displacement behavior at the interface can be explained by the model of shearing force-shear displacement relationship in connection of precast concrete.
