DEVELOPMENT OF LONG-STROKE AND COMPACT VIBRATION TESTING SYSTEM FOR TRACING EARTHQUAKE RESPONSE IN LONG-PERIOD BUILDINGS

Abstract

This paper presents the development of a long-stroke vibration testing system for tracing earthquake response in long-period buildings. Comparing with ordinary shaking tables, this system doesn't require large space and any special power supplies. In the process of development, various types of shaking tests for checking performances of this system are operated. Finally, it is confirmed that this system can precisely trace any kind of waves within the range of ±3m displacement, 500cm/s velocity and 2000cm/s² acceleration. For building users, owners and engineers, it is expected to have proper understanding on earthquake response in long-period buildings by using this system.
