Harnessing the concept of inertial amplification, an amplifier coupled base isolator (IABI) is proposed in this paper. The seismic performance, terms story drift, shear reduction, has been compared with that classical (CBI) and inerter-based isolation system (Inerter-BI). A thorough analytical study, implementing rationals random vibration for harmonic Gaussian white noise conducted to identify...

Seismic isolation is at the present time in a very active state ofdevelopment. Many new types of isolation systems are being exploredand elastomeric isolators, the system which has been employed onalmost all isolation systems completed to date, continue to undergoimprovement. At least one dozen large projects, either new or theretrofit of existing buildings, have been comple...

The aim of this paper is to assess the effectiveness nonlinear viscoelastic damping in controlling base-excited vibrations. Specifically, focus on investigating robustness base isolation performance system response due a wide set possible excitation spectra. dynamic model derived study simple structure whose provided via Rubber-Layer Roller Bearing (RLRB) (rigid cylinders rolling rigid plates w...
