At present, girder end expansion joints of long-span railway steel bridges mainly include sliding tie type expansion devices, through-beam type track expansion devices and transition plate type girder end expansion devices. In China, the sliding tie expansion type device is widely used in arch bridges and cable-stayed bridges, including two types namely through-type expansion joint and deck-type expansion joint. Domestic TSSF girder end expansion joints are the major through-type joints used whereas BWG SA60 made in Germany is the major deck-type joints used.
