Study on Influence of the Truss Bridge’s Nature Frequency by Added Masses
Due to the role of the vehicle, the large-span bridge’s frequency which is according to the bridge monitoring data is actually the vibration frequency of the vehicle-bridge coupled vibration system, but not the bridge’s natural frequency. This paper gets formulation of the added mass and the beam’s natural frequency according to the added mass of the beam’s vibration equation; and the formulation is tested by experiments and numerical simulation of a large-span steel truss bridge model. Result shows that added masses which have the fixed location are linearly proportional to changing values of the bridge’s nature frequency.
