摘要: 鋼管混凝土框架-鋼板剪力墻核心筒-黏滯阻尼墻減震結(jié)構(gòu)是一種適用于超限高層的新型結(jié)構(gòu)體系. 以京東智慧城超高層辦公樓為例,參考«建筑抗震設(shè)計(jì)規(guī)范»(GB 50011—2010)、«建筑結(jié)構(gòu)抗震性能化設(shè)計(jì)標(biāo)準(zhǔn)»(T/ CECA 20024—2022)與美國(guó) FEMA-356 標(biāo)準(zhǔn),分別基于承載力與變形指標(biāo)設(shè)定結(jié)構(gòu)抗震性能目標(biāo),對(duì)此結(jié)構(gòu)進(jìn)行多遇地震水準(zhǔn)與罕遇地震水準(zhǔn)的抗震性能評(píng)價(jià). 分析計(jì)算結(jié)果表明,該結(jié)構(gòu)滿(mǎn)足預(yù)期的性能目標(biāo)要求,最大層間位移角小于規(guī)范限值,在多遇地震水準(zhǔn)下結(jié)構(gòu)保持彈性,在罕遇地震水準(zhǔn)下結(jié)構(gòu)構(gòu)件損傷分布合理,說(shuō)明該結(jié)構(gòu)體系具有良好的抗震性能.

Abstract: Concrete filled steel tube frame-steel plate core shear wall-viscous damping wall energy-dissipated structure is anew structural system suitable for out-of-code high-rise buildings. Taking the super high-rise office building of JingdongIntelligence City Project as an example, referring to the code for seismic design of buildings ( GB 50011—2010), thestandard for seismic performance design of building structures ( T/ CECA 20024—2022) and the American FEMA-356standard, the seismic performance objectives of the structure were set based on the bearing capacity and deformationindexes. The seismic performance assement of the structure was carried out under frequently occurred and rare earthquakes.The analysis and calculation results show that the structure meets the expected performance objective requirements. Themaximum inter-story drift ratio is less than the code limit value. The structure remains elastic under frequently occurredearthquake, while the damage distribution of structural component is reasonable under the rare earthquake, indicating thegood seismic performance of the structural system.
