Question:

I am unable to get combined live load case force effects when I use the combined option in the live load tab, screen shot shown below:


The influence tracer shows only the truck and not the lane load.


Answer:

It is noted that the vehicles are assigned to the same lane. Essentially, it isn't possible to load the same lane with 2 different vehicle simultaneously, because practically this isn't possible.
I do understand that in this case, 1 vehicle represents the UDL and other represents the axel loads. But, if the combined effects need to be seen, then another lane has to be defined at the same position and the other vehicle has to be assigned to this new lane.
With this done, the combined effects would be seen.
