The main works are as follows: 1 The developingt history of the traffic load on bridges is represented. Typical bridge codes in some countries are discussed and these traffic load models are comparative analyzed. Analysis shows that the influence of layout axle for the total traffic load effect on bridge gradually becomes smaller with the increase of bridge span. So most national norms use the distributed load as the equipollent load of traffic load.
