EXPERIMENTAL STUDY ON ENERGY RESPONSE OF BASE-LSOLATED STRUCTURE
|
´˜^i‰pjF
Correlation between the peak displacement of isolator and earthquake input energy has been detected by investigations of a series of analytical results, and it is applied to a simple design procedure for base-isolated buildings. In this paper, the correlation of those values is studied using the experimental results obtained from earthquake simulator tests of a 1/2.5-scale model of an existing base-isolated, three-story reinforced-concrete building. Previously-proposed three definitions for earthquake input energy, which are total input energy, instantaneous input energy and instantaneous damage energy, are applied to the experimental results . The instantaneous damage energy gives the best correlation among those three definitions for earthquake input energy.
