I seem to be having a problem where Caesar is reporting no loads on my supports (even with Water filled condition).

I have attempted sensitivity checks by making the pipe weight heavier but there is no change to the results.

I am using version 5.10.01

If anyone has any suggestions please let me know.

I suggest that you either add your model into your post or properly describe your model, support type(s) and load cases to be able to get some guesses. Otherwise you will not be able to get a satisfactory answers. My questions are:

1. Does your model belong to an above ground (AG) or buried pipe?
2. If it is an AG pipe model and the support does not have an uplift restraint, do you think the pipe is lifted at this particular support location even for the sustain case?

If this is a buried pipe model, you will not get any SUS load on the buried section of pipe. Please do not ask why? I suggest you to read the user's guide.

Hope it helps.

Have you included weight in your load case definition ?
