| Outline of Final Research Achievements |
The objective of our study is to develop a rational seismic design method of base-isolated buildings considering the collision against retaining walls during unexpected large inland shallow earthquakes. First, we grasp the dynamic response behavior of base-isolated buildings after the collision based on shaking table tests. Next, it is demonstrated that the maximum deformation of the isolator is efficiently estimated from a theoretical solution of a nonlinear single-degree-of-freedom system subjected to sinusoidal pulse. Finally, an approximate method to estimate the maximum deformation of a building modeled by the multi-degree-of-freedom system considering the effect of the collision against retaining walls and induced higher mode response of the superstructure.
