外文摘要：This paper explored a kind of new bolt shear connector connected steel girder with prefabricated hybrid fiber reinforced concrete (HFRC) slab. Because the prefabricated HFRC bridge slab has some outstanding advantages in crack resistance, impact toughness, high tensile strength and facilitating bridge slab replacement, the composite girder with prefabricated HFRC slab is capable of potential application in the engineering practice. However, the static properties of the bolt connector transferring shear force between steel girder and prefabricated HFRC slab were the key problems to engineering application and design. This paper studied the static properties of the steel-HFRC bolt connector through pushout test. The results showed that the bearing capacity and initial stiffness of the bolt connector were improved after the fibers were incorporated, and the ultimate slip was not various. ? 2021 Taylor & Francis Group, London.
