Analysis of the Impact Effect of the Suspender System in a Half-Through Concrete Filled Steel Tubular Arch Bridge
The simulation models concrete filled steel tubular arch was constructed by using a finite element software, the 1/4 vehicle model and vehicle vibration equilibrium equation were derived by D Alemberts principle, samples of each bridge roughness were created by using the discrete Fourier transform method, the effect of bridge roughness and vehicles speed on the impact coefficient of the suspenders. The results showed that the bridge roughness had a strong influence on the impact coefficient of the suspenders; the impact coefficient fluctuated with a raise of vehicles speed; the dynamic internal force of the suspenders obviously increased with the shortening length under the vehicle load. Theory basis can be provided for the fatigue fracture inclination of the middle and short suspender in the half-through and through bridge, and a reference can be provide for the bridge design, maintenance, management, survey and evaluation.
