The orthotropic steel deck plate is used as the first bridge deck structure of the steel bridge, has the outstanding advantages of light weight, high strength and the like, and is widely applied in China.
The steel bridge deck has large longitudinal and transverse rigidity difference, complex construction details, numerous welding seams and prominent stress concentration problem, and causes frequent fatigue cracking problem of the steel bridge deck. Fatigue cracking obviously reduces the service quality of bridge structures and seriously jeopardizes the durability and safety of the structures. The fatigue problem of the orthotropic steel bridge deck is always a research hotspot in the bridge engineering world, and the fatigue test is used as the most direct and effective method for researching the fatigue performance of the steel bridge deck, is always a focus of various universities and scientific research institutes, and is mainly a full-scale segment test piece model of a plurality of U-shaped ribs and a plurality of transverse baffles, wherein the stress mode of the full-scale segment test piece model is closest to that of a solid bridge. However, the full-scale segment model has large size, multiple consumables, high energy consumption, high requirements on test equipment and sites, high test cost and other factors, so that the development of the fatigue test research of the full-scale segment test piece is restricted.
Because the full-scale section test piece model is restricted by various conditions, researchers select a single-U-rib or multi-U-rib type top plate and a U-rib local test piece to develop model test research, but the U-rib in the local test piece model is not constrained, and is different from the stress mode of the U-rib in an actual bridge, so that the actual stress condition of a tapping bridge panel can not be reflected. Therefore, a fatigue test device which can simulate the actual stress mode of the steel bridge deck and greatly reduce the size of the test piece model is needed at present.
