Sap2000 - model moving load in two path simultaneously
Sap2000 - model moving load in two path simultaneously
(OP)
Hello,
I have a 3D bridge structure as shown in the image below.

Basically the train will transfer the load to the two longitudinal beams that you can see in the inside of the bottom level of the
bridge. These elements then transfer their loads to the transverse beams, and then they transfer the load to the two
principal longitudinal beams.
I want to model the train as a moving load that travels through the two longitudinal elements described above (rail).
I know how to do that for a single line path, but dont know how to do it so that it loads both rails simultaneously. I dont know if there is a way to define a single path in the middle of the bridge and some option to tell the soft to give half the load to each of the rail, or If I should assign the moving load to two path one for each rail, but in this case, which I think is more reasonable, how can I tell the soft that the load should move in the two path at the same peace, or that is done automatically?
Dont know if there is a better option to represent this load in the full 3d model?
thanks!
