Innovative Method for Buildings Protection to Seismic Actions

Abstract

The base isolation method is increasingly used for the seismic protection of buildings due to its advantages over the conventional design. The paper presents a comparative study between two seismic isolation systems. The first system is composed of high-damping rubber bearings and linear fluid viscous dampers (HDRB+LFVD) and the second system is composed of triple-pendulum friction bearings (TPFB). The study shows that the displacements and base shear forces of the isolated structure, with the two isolation systems, have close values. With the isolation system composed of high-damping rubber bearings and linear fluid viscous dampers are recorded the minimum accelerations, both at the level of the isolation plane and at each level of the building.
