［摘要］高阻尼隔震橡胶支座是一种具有良好耗能能力的新型隔震支座。针对高阻尼隔震橡胶支座进行了竖向压缩性能试验、水平剪切性能试验、水平剪切相关性试验和极限剪切性能试验，并将试验结果与按规范计算结果进行了对比分析，考察了支座截面形状对滞回性能的影响。结果表明：高阻尼隔震橡胶支座的滞回曲线饱满，剪应变和压应力的变化对支座水平等效刚度和等效阻尼比的影响较大，加载次数对支座隔震性能影响较小。

Abstract:High damping isolation rubber bearing is a new type of isolation bearing with good energy dissipation capacity. The vertical compression performance test, horizontal shear performance test, horizontal shear correlation test and ultimate shear performance test were carried out for the high damping isolation  rubber bearings, and the test results were compared and analyzed with the calculated results according to the specification, and the influence of the bearing cross-sectional shape on the hysteresis performance was investigated. The results show that the hysteresis curve of the high damping isolation  rubber bearing is full, and the changes of shear strain and compressive stress have great influence on the horizontal equivalent stiffness and equivalent damping ratio of the bearing, while the number of loading times has less influence on the isolation performance of the bearing.

Keywords:high damping isolation  rubber bearing; vertical compression stiffness; horizontal equivalent stiffness; equivalent damping ratio; correlation
