| Research Abstract |
The purpose of this study is to examine the behavior of seismically isolated buildings under multi-dimensional earthquake input, which has been expected to be an effective preparation for large earthquake coming. First, we conducted the bi-directional loading tests for seismic isolation devices, and captured the mechanical behaviors of those devices. An analytical mechanical model was developed to allow it to reproduce the three dimensional interactive behavior for bidirectional horizontal displacements and vertical axial force variation. Subsequently, we constructed a seismic response analysis system for seismically isolated building under multi-dimensional seismic inputs by implementing the open source structure analysis system, OpenSees. Finally, we clarified the seismic performance of isolated buildings under multi-dimensional seismic input by using this analysis system.
