中文摘要: |
对直径为1 500 mm的高阻尼隔震橡胶支座(HDR1500支座)的力学性能测试值与设计值进行对比研究。结果表明:HDR1500支座的水平性能剪应变相关性测试值与设计值偏差在±20%以内,竖向压缩性能、水平性能剪应变相关性、水平性能频率相关性和反复加载相关性测试值均满足EN 15129:2018要求;各支座力学性能偏差较小,稳定性好。 |
英文摘要: |
The mechanical properties of the high damping rubber isolation bearing(HDR1500 bearing)with the diameter of 1 500 mm were tested and compared with design values. The results showed that,the deviation of the test values the shear strain dependence of horizontal characteristics from the designed values
was within ±20%. The test values of the vertical compressibility,shear strain dependence of horizontal characteristics,frequency dependence of horizontal characteristics and repeated loading dependence all met the requirements of EN 15129:2018. The deviation of mechanical property of the bearing was small,and its stability was good. |
