Traffic loads can be defined/applied in a very comfortable way. On the one side, the traffic load is automatically applied in accordance with the selected standard. On the other side, the generic approach of live load definition implemented in Allplan Bridge allows the user to consider any type of moving load.
The definition of the traffic load is split into 2 steps. First the carriageway needs to be split into notional lanes. This can be done manually or automatically. When using the automatic approach, the user needs to select the standard and the parametric lines defining the carriageway. This allows the product to evaluate the number of lanes and their width.
In the second step, the load trains (moving loads) need to be specified. The user can here also manually define an arbitrary train or use the predefined and standard dependent load trains.
As final step, the load trains need to be combined with the corresponding lane. This step also activates the calculation of moving load (influence line evaluation).
