ESTIMATION OF EARTHQUAKE RESPONSE OF A BUILDING USING AN ACCELEROMETER

Abstract

We propose a new method to estimate maximum story drift angle during a large earthquake using only one accelerometer. The method is based on the assumption that the maximum response is mainly due to low modal components. However, the use of only first two modes was found erroneous. In this paper, we propose adding rigid body motion components in addition to first two modes. Simulation and experiments results confirmed the feasibility of the method.
