Theoretical Analysis for Effects on a Base-Isolated High-Rise Building
In this paper, three-Dimensional finite element analysis was used for the research of a base-isolated high-rise building. After studying the effects of different structural systems, action of bidirectional earthquake wave, P-Delta effect and acceleration responses on it, some useful conclusions are given as follows: in the same structural systems, the story shears of the isolated structure are one order of magnitude less than those of the non-isolated structure under the action of the same seismic waves; the story displacements of the isolated high-rise frame-shear structure and those of the isolated high-rise shear wall structure are different under the action of the same seismic waves; under the action of different seismic waves, the earthquake responses of the same structural system are quite different; the effects of bidirectional earthquake waves on some components should be considered; P-Delta effect can be ignored in the base-isolated building; and the acceleration responses of the isolated high-rise building are different from those of the non-isolated counterpart. Results show that the technology of base-isolation can be applied to the high-rise building system.
