［摘要］針對(duì)某超高層鋼結(jié)構(gòu)既要滿足抗震要求，又要滿足抗風(fēng)要求，采用黏滯阻尼器對(duì)其進(jìn)行消能減震（振）設(shè)計(jì)。用ETABS軟件分析了結(jié)構(gòu)在10年一遇風(fēng)荷載、50年一遇風(fēng)荷載、多遇地震作用下結(jié)構(gòu)響應(yīng)；用Perform-3D軟件分析了結(jié)構(gòu)在罕遇地震下的響應(yīng)。分析結(jié)果表明，黏滯阻尼器改善了結(jié)構(gòu)在風(fēng)荷載下的舒適性，顯著降低了結(jié)構(gòu)在風(fēng)荷載作用下的響應(yīng)，也使地震響應(yīng)有所降低，同時(shí)延緩了結(jié)構(gòu)塑性鉸的出現(xiàn)，對(duì)結(jié)構(gòu)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
