中文摘要：

经过2008年汶川大地震后，阻尼器正在越来越多地被应用于中国的各种新建结构设计以及既有建筑的改造加固之中。根据中国相关规范的要求对5个日本生产的粘弹性阻尼器进行了动力荷载试验并对该型号阻尼器的性能进行评估，对相关中国规范中对于阻尼器性能指标的要求进行了详细介绍并对阻尼器进行了参数识别。试验中对阻尼器进行评估的项目包括外观质量、尺寸偏差、最大阻尼力、表观剪切模量、损耗因子、滞回曲线、表观剪应变极限值、频率相关性、极限荷载下的性能以及反复荷载下的性能。试验结果表明，该种阻尼器具有良好的力学性能，满足中国规范的相关要求，可以应用于建筑结构抗震及抗风设计。对于该阻尼器在整体结构中的应用研究还有待于进一步的开展。

英文摘要：

After 2008 Wenchuan Earthquake, dampers are increasingly applied in the design of new buildings and retrofit of existing buildings in China. In this paper, five viscoelastic （VE） dampers from Japan were tested under dynamic loads to evaluate their performances according to Chinese codes and standards. An identification procedure was proposed to identify these performance parameters. The performance evaluation criteria, including appearance quality, dimension deviation, maximum damping force, pseudo-shear modulus, loss factor, hysteresis curves, ultimate value of pseudo-shear modulus, frequency-dependent capacity, and capacity under ultimate and repeated load, were introduced in detail. It is concluded that the VE dampers generally meet the requirements of Chinese codes and can be used in engineering structures. Further study is needed for the application of the damper in the whole building structures.
