| To improve design and construction of composite prestressed concrete girders, a mechanism of shear transfer at the horizontal interface was reexamined. In the research, interface shear tests of three girders were conducted. The slip loads due to interface shear failure of the composite girders were well estimated using a method based on cohesive strength for joints between concrete. In particular, it was found that the influence of the normal stress due to loading should be considered for estimating the slip load of the girders. |
