Bridge load optimisation is selected in the Analysis wizard.

This dialog is accessible from the Model > Bridge modelling > Expand bridge loading menu command. This allows the user to generate a series of grid point load equivalent to the static bridge loads and/or moving bridge loads defined in Static bridge load and Moving bridge load tables. Load cases are created in the order of the bridge loads appear in the table. For static bridge loads, the grid point loads generated from each group will have the same load case number. For moving bridge Loads, the grid point loads generated by each increment of the moving bridge load will have a new load case number. Note that changes to the bridge loading table, or to the vehicles and alignments referred to in it will not change the grid point loads already generated.

This dialog is accessible from the Model > Bridge modelling > Generate static vehicle load menu command. This allows the user to generate a set of loads for a statically positioned vehicle. The origin of the vehicle (normally the centre of the back axle) is positioned is this dialog.

This dialog is available from the Model > Bridge modelling > Optimise path loading menu command. This allows the user to generate a series of static bridge loads, based on the results of an influence analysis and the data in the path loading module. For each node influence effect, beam influence effect and each entry in the Path loading table, two groups of Static bridge loads are generated, to give the most positive and most negative effect (force/displacement/reaction). Each of these groups can then be used to generate a load case comprising grid point loads using the Expand bridge loading tool.
