摘　　要：为了研究隔震层位置变化对减震效果的影响,本文针对咸阳市某框架结构教学楼建筑,在SAP2000有限元分析软件中分别建立传统抗震结构、基础隔震结构、层间隔震结构、顶部隔震结构模型,进行仿真模拟分析,对比其加速度、层间剪力、层间位移的变化规律。结果表明,随着隔震层位置向上移动减震率逐步减小。In order to study the isolation layer position changes on the shock absorption effect, In this paper, aiming at certain xianyang frame structure buildings construction the finite element analysis software SAP2000 in traditional anti-seismic structure, base isolation structure is set up respectively, inter-val of top structure and isolation layer structure model, simula-tion analysis, comparing its acceleration, interlayer shear force and displacement between the layers. The results show that with isolation layer position move upward shock absorption rate de-creases gradually.
