本研究以一高层建筑为研究对象，以一简化模型为基础，探讨其隔震系统之特征值及风振反应之准确性。针对基础隔震系统上方的建筑物建立了简化模型。用两个或多个质量体系模拟建筑物，可以准确地估计建筑物首层的顺风向位移。对于横风向和扭转风振响应，采用质量数较少的简化模型计算位移与采用质量数较多的简化模型计算位移相比，存在较大的误差。
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 reduced models are made targeting buildings above the base isolation system. The along-wind displacements at the first floor of a building are estimated accurately if the building is modeled by two or more 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.
