Solution seems to be different from the experimental result
Hello, I am doing an analysis on a cold formed steel beam-to-column bolted connection with gusset plate. In this analysis, I need to verify the result granted by ANSYS with the result of the experimental that has been done before. I am doing the analysis using Static Structural in ANSYS Workbench, using properties with young modulus and bilinear isotropic hardening data from the same experimental test. But, after I did the analysis, the result I get doesn't seem to be matching the experimental result. Max P-def of the experimental is 32kN with deformation of 85,83 mm. But I could only get the structure to get nonlinearity behavior over 30 kN, which after I test, I need almost 3 times of the actual load to get the same deformation result. What have I done wrong? Any suggestion? I am using Nonlinear Mechanical Mesh with 15 mm size. If any photo is needed, I would happily attach it in this forum, thankyou very much. Any tips would be appreciated🙏.
