| 中文摘要: |
| 对隔震橡胶支座竖向刚度试验进行研究，考察不同加载方式和加载次数对竖向刚度测试结果的影响，利用2种标准差分析方法对竖向刚度测试结果的一致性进行评价。结果表明：在连续加载方式下，首次加载时隔震橡胶支座的竖向刚度偏小，随着加载次数的增加，竖向刚度基本保持不变；用单独加载方式测得的竖向刚度小于用连续加载方式测得的竖向刚度；采用载荷、位移标准差分析法和刚度标准差分析法的分析结果基本一致。 |
| 英文摘要: |
| The vertical stiffness test of rubber bearings is carried out. The influence of different loading times and different loading modes on the vertical stiffness of the bearing is studied, and the consistency of the stiffness is evaluated by using two different standard variance analysis methods, the results show that under continuous loading, the vertical stiffness of the bearing remains constant with the increase of loading times, and the vertical stiffness of the bearing under single loading is smaller than that under continuous loading. |
