In recent years, fatigue damage at rigid connections in steel bridge piers has been reported. In this study, the live load modification factor to be used for the piers which support a continuous beam and simple beam was examined. Both the imitative traffic flow determined by Monte Carlo simulation and the representative load (T-load) were applied on the continuous beam and simple beam. And the simultaneous loading factor and the T-load modification factor were obtained by comparing fatigue damages for each loading case. Finally, the predominant parameters were revealed and calculation formulae of both factors were proposed.
