Study on Dynamic Characteristic of 64m Railway Steel Truss Bridge on the Different Speed of Train Loads

Abstract:

Through theoretical calculation, systemic analysis of dynamic performance of the 64m single and double line railway steel truss bridges on the different speed of train loads. Contrast and analysis the main dynamic performance parameters of bridges on the differend speed. In 64m steel truss bridges in Heavy-Haul Coal Line application practice proves that the deflection of the bridge to the speed is insensitive. The vertical acceleration and horizontal acceleration is sensitive to speed. The speed 80km/h is the speed which lead to the maximum vertical acceleration of the single line and double line in light-load condition.
