i did the Static pushover analysis for four model that The only difference of them was number of integration sections. I I've measured the curvature in section 1 in same beam at 50 cm displacement. that the results were as described.

Hello
I have checked this issue several times in four models in target displacement for Similar section.this section there is at first of element.
for 3 integration sections, curvature is 0.02
for 5 integration sections, curvature is 0.04
for 8 integration sections, curvature is 0.09
for 10 ...

Hello
In the sections of the concrete beams and columns that riched to the yielding limit, by changing the number of integration sections in FB element the curvature changes greatly . For example, with 3 integration sections curvature
is 0.01, but with ten integration sections in the same section ...
