Seismic Response Characteristics of Full-Size Buildings with Base Isolation System
- Argonne National Laboratory (ANL), Argonne, IL (United States)
This paper investigates the response characteristics of full-size reinforced concrete buildings via numerical simulations and actual observations. The test facility consists of two identical three-story buildings constructed side by side at Tohoku University in Sendai, Japan. Since the installation of high-damping isolation bearings in April 1989, data from over twenty earthquakes have been recorded. In this paper, three representative earthquake records, #2, #6, and #17 are used to study the detailed response characteristics. Numerical simulations are carried out with the system response program, SISEC. In general, good agreement has been found between numerical solutions and actual observations. Both results indicate that the advantage of the isolation system for small earthquakes is insignificant. For relatively large earthquake motion, however, such as from record #6 earthquake, the effect of isolators in mitigating the acceleration response becomes more pronounced. Also, both analysis and observation have demonstrated that the isolation system installed in the Sendai Building is very effective. The system is stiff enough to prevent the building displacement under minor earthquakes and wind loads, but is relatively soft for reducing the acceleration response during earthquakes with moderate and strong ground motion.
