Different Integration Sections results

[MOUMTZIS IOANNIS]

I' m running a static pushover analysis.
The elememt classes I had where separated in 5 Integration Sections when I run the analysis.
But as my structure's elements where subdivided in 4 different sections I changed the value to 3 Intergration Sections to all element classes.
The results I had weren't the same.
Increased values occured (about 10% increasement).
Why is that happening?

Dear Ioannis,

Please refer to the discussion in the Help System ('Material Inelasticity' section) for hints and literature references on the issue of analysis sensitivity to integration points selection.
