Fatigue performance of composite joint for double-deck composite truss bridge
A 1:4 model is made to study the fatigue performance of the composite joint for double-deck composite truss bridge. The test results show that the joint remains in a linear elastic state under the fatigue loading. Under constant amplitude loading, the stiffness of the joint reduces gradually. The number of cracks at the interface of steel and concrete is small and the crack length propagates slowly. This study shows that the composite joint has enough fatigue strength and fatigue life. It is also expected that the results presented in this paper would be useful as references for the further research and the design of truss bridge and composite joint.
