please help me,I am confused.
I modeled two shear wall with a steel beam coupled them under cyclic loading. but i have a problem.i am going to verify my model with a test program. i must control beam "force - displacment" curve (that is a hystersis curve)With that obtained from testing,but my curve (obtained abaqus) haven't any degradation at consecutive cycles .
what reasons are for this problem? why i have'nt any stiffness degradation in my model.
i define damage parameter :dt=1 - ft/ft0 and dc=1 - fc/fc0. what i should devote to stiffness recovery ( compression and tension recovery).
