I have a abaqus simulation about reinforced concrete frame, but my displacement result is very big, I have checked CDP model but I don't think CDP model has such big displacement effect. What should I check? Thank you very much.
If your Abaqus values consistently double the experimental results, then you probably mistakenly placed a property or load value in the code that is half or double what it should be.
I think you should check support conditions and loading conditions. Then you can check your material data. Or when you export data then there have some misconcept .
