Baseshear-displacement curve not degrade while all Nonlinear link yield
Posted: 23 Apr 2024, 05:43
Hi
I'm running Static time history analysis on steel frame (pin base with Nonlinear link at all Beam-column joints) by applied lateral and to monitoring Base shear-displacement curve in global response.
I found that all of my nonlinear link was yielded but the structure capacity curve did not degrade and still linearly increase although I apply very large lateral displacement.
Could you suggest the possible error I made on my model?
Thanks
