摘　　要：非线性黏滞阻尼器性能试验是控制其质量的重要手段,而我国非线性黏滞阻尼器性能测试标准的部分技术规定尚需进一步明确和细化。针对性能参数C、α确定、滞回曲线面积评定及慢速试验实施等争议较多的问题,分别从测试技术和数据处理两方面进行探索研究。通过对工程常用非线性黏滞阻尼器开展性能试验,明确了性能参数C、α的数据处理方案,统一了地震疲劳性能试验评定滞回曲线面积的技术规定,细化了慢速试验实施的技术要求。研究成果可供非线性黏滞阻尼器性能试验技术标准完善参考。Performance test on non-linear viscous damper is an essential way to assess its performance.However,part of the technique provisions in the codes of practice associated with performance test on non-linear viscous damper has not been specified and detailed.There are still a few controversial issues of determining the performance parameters C andα,assessing the area of hysteresis loop,conducting low-velocity test,etc.In view of these,this study examined both the associated test technique and data processing approaches.Based on a series of test on the typical nonlinear viscous damper in engineering practice,a data processing scheme was determined for the performance parameters C andα.The technique provision about assessing the area of hysteresis loop and conducting low-velocity test was then specified.The results of this study will provide guidance for improving the technique provisions for assessing the performance of nonlinear viscous damper.
