    Abstract
  • In order to study the deformability of Perfobond Leiste (PBL) shear connectors, a series of tests were conducted to investigate the load-bearing mechanism and deformability influence factors of PBL shear connectors. In these tests, 33 specimens divided into 4 types and 9 groups were loaded, and the external loads, deformation, and failure pattern of the specimens were probed. On this basis, the yield load of the PBL shear connector was defined, and a formula for yield load calculation was proposed. The results show that the deformation behavior of PBL connectors can be divided into the pseudo-elastic stage, the elasto-plastic stage, and the yield stage; and the yield is due to the shear fracture of concrete column. The slide at the yield point is about 1.2 mm. Load is carried by concrete column and transverse steel bar in the pseudo-elastic stage and elasto-plastic stage, but only by transverse steel bar in the yield stage. Therefore, the diameter and strength of the transverse steel bar and the diameter of concrete column are the main factors influencing the deformation behavior of PBL shear connectors, and the diameter of the transverse steel bar should be more than 16 mm.
