THE MECHANICAL BEHAVIOR OF PRESTRESSED CONCRETE GIRDER WITH STEEL PLATE

Abstract

A prestressed concrete girder with a steel section in its compressive zone is developed for bridges. The girder has an advantage of having less depth than the ordinary prestressed concrete girder. This paper reports about bending, shear and fatigue behavior of the girder based on experimental data. The connection between steel and concrete is achieved by introducing holes in the steel section. The paper also reports ‘Push out test’ performed to ensure the strength of these connections.
