Hello Sandip, If you be so kind as to NOT change node points and models under review. Answers and comments will based on same bend node, A03, from the model you had posted, 1762_DOWN_Archive.APC. I may have confused this issue with my previous reply and apologize about that. Let me try to make things clearer. From Analysis summary: For analsysis set #1: Load sequence = Gr > U1> T1> P1. Please see results grids for node point A03. Per your operating conditions, GU1T1P1 displacement is 0.00mm. Let us consider load sequence one step at a time. First Gravity, Gr, load case causes point A03m to moved down, -22.354mm (total displacement = - 22.354mm) because there is an infinite gap below on A03m V-Stop support. see image below for support details. At this point, the distributed load is applied over the entire segment A00 - A06 causing node point A03m to move up 1.006mm (total displacement = - 21.348mm). Next T1 load case is applied to segment A, this thermal expansion causes the node point to move up, +21.348mm (total displacement = 0.00mm) until it makes contacts with the support. Thus causing the load on the support in +ve Y-direction. Again, this is a simple case of load sequence where the user should be referring to the operating conditions (ex. GU1T1 or GrU1T1P1, etc..), for actual displacement of the model and then only considering the individual load cases (ex. T1) in trying to understand the operating condition values. Remeber for Linear analysis the rules are completely different (see AutoPIPE help for details).
