Most unfavourable load position from running load

Dear all,

I calculated running load on my structure and i would like to choose load position for every structural elements which causes the bigest internal forces. I need the critical load position for further calculation. Can you give me any advice how to do it?

For example there are the corss beams and i calculate the sercive vehicle load from EN for pedestrian bridges. I would like to choose one load position which cause the biggest bending moment in the whole structure.

TRAC function in module MAXIMA can do that, but you have to know where(element no.) is the maximum of bending moment.
