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,首次加载时测得的隔震橡胶支座竖向刚度偏小,第2次加载时竖向刚度增大,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。The vertical stiffness test of isolation rubber bearings was studied,the influence of different loading methods and loading cycles on the vertical stiffness test results was investigated,and the consistency of the vertical stiffness test results was evaluated by using two standard deviation analysis methods. The results showed that,under the continuous loading mode,the test result of the vertical stiffness was relatively small at the first loading,and then it increased at the subsequent second loading,however,with further increase of loading times,the test result basically remained unchanged. The vertical stiffness measured by individual loading was less than that measured by continuous loading. The evaluation results obtained by using the load,displacement standard deviation analysis method and the stiffness standard deviation analysis method were basically consistent.
