Hi

I try to apply a moving load (=10^8N) on on a bridge model using transient analysis, but i get very different results compared to statical analysis

I think the problem is related to the time increment and the number of substeps parameters

Hello,

Can you elaborate on how the results are different? What were you expecting? If you leave out the transient part from the response of transient analysis then do you see similarity in steady state portion of the response when compared with static analysis results?

i would first to thank your for your reply ,

In fact, i have applied the moving load on the named selection "noeuds hourdis" that contains 2240 nodes using different values of end time and time increment, but results of deformation of the deck were very lower (0.002m) than those of the statical analysis (3.44m)

So i think that the force is not correctly applied on the different nodes !

Please could you explain how to set these parameters in this case

Can you share snapsjot of how you applied the forces in both analysis types?
