The efficiency of vibration reduction of Triple Friction Pendulum together with Magneto Rheological damper connected adjacent buildings under earthquake
This paper studies the efficiency of vibration reduction of Triple Friction Pendulum (TFP) at the bottom of column combine with Magneto-Rheological (MR) damper between two structures due to ground motion in earthquake. The MR damper is modelled by springs and viscous dampers, the damping f...
