The impact of different shear connectors (perfobond leisten (PBL) shear connectors and stud shear connectors) on the mechanical performances of prestressed concrete (PSC) composite box-girders with corrugated steel webs was studied. Mechanical properties were researched by conducting experiments on two specimens with PBL shear connectors or stud shear connectors; these properties included the ultimate bearing capacity, the flexural stiffness, crack resistance and the efficiency of prestressing of the girder. The test results showed that, compared with the stud shear connectors, PBL shear connectors greatly improved the ultimate bearing capacity, flexural stiffness and crack resistance of PSC composite box-girders with corrugated steel webs. However, regarding the efficiency of prestressing, the PBL shear connectors did not perform as well as the stud shear connectors.
