The objective of this experiment is to demonstrate the response of base-isolated buildings subjected to dynamic loading. A three-dimensional, one-story building frame will be designed and constructed for the experiment. The structure will be tested in a conventional configuration in which the building is rigidly attached to the shaking table platform (foundation) and in an alternate configuration in which the building is supported on a base isolation system. Two different isolation systems will be tested; one that incorporates sliding isolation bearings and a second which incorporates elastomeric bearings. The effects of isolating the structure will be explored through system identification tests (free vibration and forced vibration), steady-state harmonic loading tests, and historical earthquake tests. The experimental results will be compared with predictions from numerical analyses. It is expected that the shaking table experiments will be utilized in a junior level Introduction to Structural Engineering course, a senior level Structural Design Laboratory course, and graduate level courses in Structural Dynamics and Earthquake Engineering.
