Abstract
This study aims to grasp the response characteristics of the roof surface and propose external forces for designing
the ceiling based on the data of E-defense shaking table test data by using real size steel gymnasium specimen. As a
fundamental study, the authors confirmed that natural frequency decreases due to damage of specimen subjected to
multiple excitation. In this paper, the mode shape is estimated from the value measured from the accelerometer on
the roof surface of the specimen using the FDD method, and the mode shape due to damage is evaluated.
