I modeled a cantilever column with two springs at the bottom. One to represent the hinge at the column-end and another to represent effects of the foundation (Fixation).
The column end-spring absorbs (output moment for this element shows) same moment as manually computed, but the other one absorbs moment (output moment for this spring/element) five times larger than computed (Applied force times the distance between, manually computation).
Note: The spring absorb larger moment is rigid-plastic.
If anyone can help to fix this, would be highly appreciated.
I not very a new to OpenSEES nor a Master in it.
