In earthquakes caused by active inland faults, fault displacement that appears on the ground surface and inertial force may affect to seismic behavior of structures at the same time. However, the seismic behavior of structures affected by inertial force and fault displacement is unexplained. In this study, shaking table test was conducted on a steel frame model subjected to inertial force and fault displacement were applied simultaneously to understand the behavior of the model under the simultaneous action of inertial force and fault displacement. As a result, it was clarified that the influence of fault displacement on the dynamic response of structures may not be negligible. Furthermore, a reproduction analysis of shaking table test was conducted, and validity of the analytical method that can consider to the effects of inertial force and fault displacement was clarified.
