Shaking table and pseudodynamic tests for the evaluation of the seismic performance of base-isolated structures

摘要

This paper describes a series of shaking table and pseudodynamic tests for the evaluation of seismic performance of base-isolated structures subjected to various seismic earthquake inputs. The main objectives of this study are: (1) evaluation of the effectiveness of base isolation systems for low-rise structures against severe seismic loads through shaking table tests; (2) verification of the substructuring pseudodynamic tests method for base-isolated structures in comparison with the shaking table test results; and (3) development of an analytical method for predicting earthquake responses of base isolation systems. In the shaking table test, a quarter-scale three-story structure base-isolated by laminated rubber bearings is tested.
