Shake Table Tests of a Coupled Primary Structure-Floor Isolation System

A small-scale rolling-pendulum (RP) isolation system with gap restrainers was tested under swept-sine surveys (chirp) of varying amplitude. These tests were used to characterize the properties of the experimental small-scale floor isolation system (FIS) that was subsequently installed in a small-scale three-story primary structure (PS). The PS-FIS system was tested under four historic ground motions through shake table testing. These tests were used to assess the coupling between the FIS and the PS. Additionally, cyclic load-displacement tests were run to characterize the response of the shock absorbers used in the FIS. All the data from these experiments have been processed to quantify the performance and characteristics of the PS-FIS and its components, as documented in the data report and in Bin (2021).
