［摘要］消能減震技術(shù)的應(yīng)用是超高層結(jié)構(gòu)抗震設(shè)計(jì)的一種新思路。以烏魯木齊綠地中心為例，介紹帶黏滯阻尼器超高層結(jié)構(gòu)設(shè)計(jì)的關(guān)鍵問題，包括阻尼器的布置方式、參數(shù)選擇以及相關(guān)構(gòu)造，整體結(jié)構(gòu)性能指標(biāo)，阻尼器耗能效果。通過彈塑性時(shí)程分析驗(yàn)證其在大震下的結(jié)構(gòu)性能。通過對減震結(jié)構(gòu)和抗震方案的整體指標(biāo)、抗震性能和經(jīng)濟(jì)性指標(biāo)的對比，說明減震結(jié)構(gòu)方案的優(yōu)越性。

Abstract:Application of energy dissipation technology is an innovation of seismic design of super tall building. Urumqi Greenland Center was taken as an example to introduce the key structural design issues of super tall building with viscous dampers, including layout of viscous dampers, parameter selection and details of viscous dampers, overall structural performance indicators and energy dissipating effect of dampers. The structural integral behaviors were investigated by elastic-plastic time-history analysis under rare earthquake. The comparisons of structural responses, seismic performances and structural costs between original seismic resistant scheme and damping scheme showed superiority of damping scheme.
Keywords:Urumqi Greenland Center; energy dissipation technology; super tall building structure; viscous damper; effect of energy dissipating; seismic performance
