Fatigue durability of composite girder bridge with channel-shaped precast PC deck slabs

The precast PC panel (PPC panel) has high quality as well as high endurance in the mechanical properties, and it has been increasingly applied to the deck slabs construction of the steel girder bridge, because of the labor saving during construction. A channel-shaped precast PC panel (CPC panel) has been developed for the purpose of an improvement of the durability against to the vehicle load and the fabrication and erection work of deck slabs in steel girder bridges on site. In this paper, three experimental studies; the push-out test on CPC panel-H steel joint specimens, the static bending failure test and the wheel running test on composite steel beam specimens, are presented, and the outline of the practical application for the composite box girder bridge with CPC deck slabs is described.
