Abstract:
      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.
