Abstract text:
The paper presents a series of experimental tests on ANCO R250-3123 shaking table from the Faculty of Civil Engineering and Building Services of Iaşi, in order to identify the structural response of a base isolated model with a multi-stage system made of four layers of elastomeric bearings. In the first phase of the experimental program, the dynamic characteristics of the structural model were determined and in the second phase the behaviour under different seismic actions of the base isolated structure with multi-stage system was evaluated. Three sinus beat actions and an artificial accelerogram were applied in the longitudinal direction of the experimental model. Following the results interpretation, a significant reduction of accelerations recorded at the top of the structure was achieved compared with the maximum acceleration recorded at the platform level. The experimental model behaved like a rigid body (the displacement values from the top and the bottom of the structure are approximately equal).
