摘要：

This study investigates the accuracy of eigenvalues and wind responses obtained from a reduced model of a high-rise building with a base isolation system. The reduceb models are made targeting buildings above the bate isolation system. The along-wind displacements at the first floor of a building are estimated S accurately if the building is modeled by two or mocre masses system. For across-wind and torsional wind response there are large errors in calculating the displacement with using a reduced model presented with a few masses in comparison with those with five or more masses.
