To analyze the multidimensional elastic–plastic response of frame structure with magnetorheological (MR) dampers under strong seismic excitations, test MRD was performed, location matrix in derived, and calculation models without an were established based on three-segment variable stiffness beam. Taking a five-story reinforced concrete (RC) as example, developed by MATLAB software dynamic time ...

In recent years, significant advancements have been made in the definition of innovative “minimal-damage structures,” chasing need for more resilient societies against extreme seismic events. this context, moment resisting frames (MRFs) equipped with self-centering damage-free (SCDF) devices column bases and beam-to-column joints represent a viable solution to improve structural resilience dama...
