［摘要］针对某超高层钢结构既要满足抗震要求，又要满足抗风要求，采用黏滞阻尼器对其进行消能减震（振）设计。用ETABS软件分析了结构在10年一遇风荷载、50年一遇风荷载、多遇地震作用下结构响应；用Perform-3D软件分析了结构在罕遇地震下的响应。分析结果表明，黏滞阻尼器改善了结构在风荷载下的舒适性，显著降低了结构在风荷载作用下的响应，也使地震响应有所降低，同时延缓了结构塑性铰的出现，对结构抗震性能的提高起到一定作用。

Abstract: To meet the seismic requirements and the wind-resistant requirements of a super high-rise steel structure, the energy dissipation design using viscous dampers was carried out. ETABS software was used to analyze the response of the structure under the wind load of 10 years, the wind load of 50 years and the frequent earthquake. Perform-3D software was used to analyze the response of the structure under the rare earthquake. The results show that viscous dampers can improve the comfort of structure under wind load and reduce the response of the structure under wind load significantly. Viscous dampers can also reduce the seismic response and delay the emergence of plastic hinge and play a certain role in improving the seismic performance of the structure.

Keywords: viscous damper; super high-rise structure; energy dissipation; time-history analysis
