Abstract

The occurrence of earthquakes in densely populated seismic zones of the world and in western Argentina, have brought to light great economic and human life losses. In order to control and minimize the damage caused by earthquakes, different seismic protection techniques based on energ y dissipation and/or seismic isolation have been developed. The research is part of a broader project that includes the design, manufacturing and mechanical and nonlinear characterization of seismic isolators, all of them manufactured with local technology. The work shows the results of the tests of different prototypes of elastomeric isolators subjected to vertical compression and horizontal cyclic loads. The results obtained are compared with those obtained through numerical analysis of finite elements. T he experimental tests allowed the validation of the proposed numerical model and also the characterization of the constitutive laws of the devices.
