| Research Abstract |
We improved the practical design of seismically-isolated structures with the state of the art analysis capabilities to capture extreme isolator behavior. First, a new analytical model was developed for the elastomeric isolation bearings under severe large shear deformation and axial load. Next, the safety of seismically-isolated buildings was carefully evaluated using the improved analytical model for long-period ground motions that might be produced by large earthquakes in the near future.
