    Abstract
  • A simply supported beam highway bridge was taken as an example, the half vehicle model with four-degree-of-freedom was employed to set up vehicle-bridge coupled vibration function, and the time-history curves of dynamic deflection and strain at mid-span under different vehicle velocities were calculated.The impact factors (IM) calculated by traditional definition method, experiment method and current code provisions were compared, the first two methods were revised to reflect the maximum dynamic response of bridge.According to the calculation principle of the maximum internal force for girder under moving load, the weighted method was utilized to replenish the first two methods.Analysis result shows that the IMs calculated by traditional definition and experiment methods are less than those in General Code for Design of Highway Bridges and Culverts (JTG D60—2004).The average value of IMs obtained at the maximum dynamic response of time-history curves doubles the first two methods, and its maximum IM is 37%less than code provision.Deflection IMs calculated by traditional definition method are greater than strain IMs, but deflection IMs calculated by experiment method are mostly less than strain IMs.The IM calculated by traditional definition method and weighted method is 16% greater than code provision.The weighted method combining with experiment method reflects the whole impact course of bridge caused by moving load, and it is stable when calculating IM.
