Fatigue Load for Semi-rigid Connection of Rail Floor Beam of Long-Span Steel Truss Arch Bridges

  • In order to estimate the fatigue damage accumulation of semi-rigid connection between the rail floor beam and truss of a steel truss arch bridge bearing light rail transit and highway vehicle loads,fatigue load spectrum,produced due to traffic loads in the designed service life of the bridge,for the semi-rigid connection was investigated.Based on the analysis of traffic loads and the AASHTO specification,a fatigue load model to reflect the actual running state of the bridge during the designed service life was established.A 3-D finite element analysis was made to simulate the load history for the semi-rigid connection.Based on the fatigue damage accumulation theory,fatigue test load for the semi-rigid connection was determined.
