摘　　要：In order to resolve affecting of Different Shear Connectors(the perfobond leisten(PBL) shear connectors and stud shear connectors) on the M echanical Properties of Prestressed Concrete Composite BoxGirders with Corrugated Steel Webs,Some mechanical properties of Prestressed Concrete Composite BoxGirder with Corrugated Steel Webs were researched by conducting experiments on two specimens with PBL shear connectors and stud shear connectors relating to ultimate bearing capacity,the flexural stiffness,crack resistance properties and the efficiency of prestressing being introduced to the girder,etc. The test results show ed that,relative to the stud shear connectors,PBL shear connectors can greatly improve some structural performance qualities of prestressed concrete composite box-girders with corrugated steel webs,such as the ultimate bearing capacity,the flexural stiffness and the crack resistance property,but when the efficiency of prestressing is introduced into the girder,the PBL shear connectors do not perform as well as stud shear connectors.In order to resolve affecting of Different Shear Connectors(the perfobond leisten(PBL) shear connectors and stud shear connectors) on the M echanical Properties of Prestressed Concrete Composite BoxGirders with Corrugated Steel Webs,Some mechanical properties of Prestressed Concrete Composite BoxGirder with Corrugated Steel Webs were researched by conducting experiments on two specimens with PBL shear connectors and stud shear connectors relating to ultimate bearing capacity,the flexural stiffness,crack resistance properties and the efficiency of prestressing being introduced to the girder,etc. The test results show ed that,relative to the stud shear connectors,PBL shear connectors can greatly improve some structural performance qualities of prestressed concrete composite box-girders with corrugated steel webs,such as the ultimate bearing capacity,the flexural stiffness and the crack resistance property,but when the efficiency of prestressing is introduced into the girder,the PBL shear connectors do not perform as well as stud shear connectors.
