摘　　要：对底部固定非隔震和底部在砂垫层上隔震的两个上部结构完全相同的竹木模型进行了震动实验,并应用测试数据成果进行了位移对比,另外,通过SAP2000软件,分析了底部固定非隔震模型,和实验数据也作了比较,结果表明,实验和软件模拟数据比较接近,非隔震的结构与隔震结构层间位移有较大差异,隔震结构明显层间位移小,但底部有较大的水平和竖向位移及转动现象。The paper carries out vibration test for two same bamboo model with fixed non-vibration isolation bottom and sand cushion vibration isola-tion bottom, carries out their displacement comparison by applying testing data achievements, uses SAP2000 software, and compares fixed non-vi-bration isolation bottom to experimental data. Results show that ： the experimental data is in accordance with software simulating data; the inter-layer displacement of non-vibration isolating structure and vibration isolating structure is different ; the displacement of vibration isolating structure is rela-tively small, however, it will occur obvious horizontal and vertical displacement and alteration phenomenon at the bottom.
