Thanks, and sorry my language! :v What I am doing is to compare an inelastic spectrum calculated from a SDOF model that I did in OpenSEES with the results of "SeismoSignal" method. This, with 5% damping and 0% post-yield stiffness (EPP), for EL CENTRO record. (The results of the model in O...

Hi, I would like to confirm if the results of the Inelastic Displacement Spectra corresponds to "yield-deformations response spectrum (u_y)" or to "pick deformations (u_m)" of inelastic system. (where ductility = u_m/u_y). I have compared my calculations of inelastic spectra (acc...
