Seismic response of a base-isolated building with high damping, low shear modulus elastomeric bearings
This paper deals with an investigation of seismic responses of a base-isolated building subjected to actual earthquakes. The isolation system consists of six medium shape factor, high damping, low shear modulus bearings designed by ANL and manufactured in the United Kingdom. The objective is two-fold: (1) to study the effectiveness of the isolated bearings through responses of the test building under actual earthquakes, and (2) to validate the 3-D SISEC (Seismic Isolation System Evaluation Code) program. Results obtained from the earthquake observations indicate that the advantage of the base-isolation system in mitigating the acceleration of the superstructure is very pronounced. For earthquakes (number sign)42 and (number sign)44, the accelerations at the roof level of the isolated building are only 20% to 30% of the ordinary building accelerations. Also, for both ordinary and base-isolated buildings the computed accelerations agree reasonably well with those recorded.
