Dear Silvia Thanks for your scripts. I am starting to do a reverse cyclic analysis on a SDOF bridge pier model where a zerolength Pinching4 hinge is built at base. I modified the codes based on my own model but the analysis failed at initial iteration. I attached the scripts and hopefully you could ...

Hi Fawadnajam, How's your work now? Have you successfully plot the inelastic spectra? I am trying to do similar stuff ...

Hi prof, where can i find source code?
Thanks
