Case:
See figure below, no top load, between node 890 and node 894 is linked by a "weak"
[attachment=229]
Aim: To obtain forces and moments at support point muur 2 – node 890 and at point muur 3 – node 891

The orientation and value are quite different if i compare these three tables, they are all using locale element coordinate systeem, which value is actually the force and moment at the support punt?
The SUPREA table gives the support reaction of external supports.
The ADDSUP table shows an additional (ground)reaction in case of gaps between the pipeline and the soil.
The CSLOAD table shows all cross-sectional loading data.
Use the help file in PLE to read more about the contents and use of those tables.

"which value is actually the force and moment at the support point?"

This depends on what you want to know:
Do you want to know the forces and bending moments in the support? --> SUPREA
Do you want to know the forces and bending moments in the cross-section of the pipeline on top of this support? --> CSLOAD

I hope this answers your question,

Yes, it is an earlier question. I have figured out what means of these tables. But still thanks for the clear answer.
